In Triangle BCD, BC=BD, and angle B =13x-35, angle C = 5x-19, angle D=2x+14. Find the measure of each angle

Answers

Answer 1

Answer:

[tex]B = 108[/tex]

[tex]C = 36[/tex]

[tex]D = 36[/tex]

Step-by-step explanation:

Given

[tex]B =13x - 35[/tex]

[tex]C = 5x - 19[/tex]

[tex]D=2x+14[/tex]

[tex]BC = BD[/tex]

Required

Determine the measure of each angle

The angles in a triangle sum up t 180. i.e.

[tex]B + C + D = 180[/tex]

Since [tex]BC = BD[/tex], then [tex]C = D[/tex]

[tex]B + C + D = 180[/tex] can then be rewritten as:

[tex]B + C + C = 180[/tex]

[tex]B + 2C = 180[/tex]

Substitute values for B and C

[tex]13x - 35 + 2(5x - 19) = 180[/tex]

Open Bracket

[tex]13x - 35 + 10x - 38 = 180[/tex]

Collect Like Terms

[tex]13x + 10x = 180 + 38 + 35[/tex]

[tex]23x= 253[/tex]

Divide both sides by 23

[tex]x = 11[/tex]

To get the measure of each angle, substitute 11 for x in the expressions of B, C and D

[tex]B =13x - 35[/tex]

[tex]B = 13 * 11 - 35[/tex]

[tex]B = 108[/tex]

[tex]C = 5x - 19[/tex]

[tex]C = 5 * 11 - 19[/tex]

[tex]C = 36[/tex]

[tex]D=2x+14[/tex]

[tex]D = 2 * 11 + 14[/tex]

[tex]D = 36[/tex]

Answer 2

The measure of m<B, m<C and m<D are 108, 36 and 46 respectively

What are triangles?

From the triangle BCD, if BC=BD, then

m<C = m<D (Base angles are equal)

Given the following paramters:

m<C = 5x-19m<D = 2x + 14

Hence;

5x - 19 =2x + 14

5x- 2x = 14 + 19

3x = 33

x = 11

m<B = 13x - 35

m<B = 13(11) - 35

m<B = 108 degres

m<C = 5x - 19

m<C = 55- 19

m<C = 36

m<D = 180 - 144

m<D = 36 degreees

Hence the measure of m<B, m<C and m<D are 108, 36 and 46 respectively

Both length and width of Devon's new rug are 2 feet longer than the original. Find the simplified expression of the perimeter and the NEW rug.​ plsssss help.me show work

Answers

Answer:

Perimeter of the new rug   = 4x+2 feet

Step-by-step explanation:

Let the length be x feet and the width of the first rug will be x- 3 feet

Area = length * breadth = x * (x-3) = x²- 3x

Length of the new rug = x+2 feet

Width of the rug = x+2-3= x-1 feet

Perimeter of the recatngle = 2( length + breadth)

                                             = 2( x+2 + x-1)

                                               = 2 (2x+1)

Find the recursive rule, explicit rule, and f(20)

Answers

Answer:

Recursive:

[tex]f(1)=4, f(n)=f(n-1)-4[/tex]

Explicit:

[tex]f(n)=4-4(n-1)[/tex]

And the 20th term f(20) is -72.

Step-by-step explanation:

We have the sequence:

4, 0, -4, -8...

Let’s find the recursive and explicit rule for the sequence.

Recursive Rule:

Let’s determine the factor by which the sequence is decreasing by. We see that each subsequent term is 4 less than the previous term. In other words, our common difference is -4.

So, this is a arithmetic sequence.

The standard format for an recursive rule for an arithmetic sequence is:

[tex]f(1)=a , f(n)=f(n-1)+(d)[/tex]

Where a is the initial term and d is our common difference.

From our sequence, we know that our initial term a is 4.

We also determined that our common difference is -4.

Substitute. Hence, our recursive rule is:

[tex]f(1)=4, f(n)=f(n-1)-4[/tex]

Explicit Rule:

The standard format for an explicit rule for an arithmetic sequence is:

[tex]f(n)=a+d(n-1)[/tex]

Where a is the initial term and d is the common difference. So, again, let’s substitute 4 for a and -4 for d. Hence, our explicit formula is:

[tex]f(n)=4-4(n-1)[/tex]

To find f(20), we can use the explicit formula. It is possible to use the recursive formula, but it gets tedious. Therefore, we will substitute 20 for n for our explicit formula:

[tex]f(20)=4-4(20-1)[/tex]

Evaluate:

[tex]\begin{aligned} f(20)&=4-4(19) \\ f(20)&=4-76 \\ f(20)&=-72 \end{aligned}[/tex]

Hence, our 20th term is -72.

Find all real square roots of 25

Answers

Answer:

All real square roots of 25 is +5 and -5.

Step-by-step explanation:

When you square root something, you take the positive and negative of the number, so the square root of 25 would be 5 and -5.

When you do 5 times 5, you get 25 and when you do -5 times -5, you get 25 as well, this is why we do the negative as well.

#teamtrees #WAP (Water And Plant)

How to find the closest integer less than and greater than the square root of a number?

The function is strictly increasing function for x ≥ 0.

Assuming that all the values of x are ≥ 1, whenever there is increment in the value of 'x', the value of y increases too Perfect square are those integers whose square root is an integer. Let x-a be the closest perfect square less than x, and let x+b be the closest perfect square more than x, then we get: x-a < x < x+b (no perfect square in between x-a and x+b, except possibly x itself).

When we do square root of something, we take the positive and negative of the number, so the square root of 25 would be 5 and -5.

When we do 5 times 5, we will get 25 and when we do -5 times -5, we will get 25 as well, this is why we do the negative as well.

Hence, all the real square roots of 25 are 5 and -5.

The measures of the angles of a triangle solve for X

Answers

Answer:

x = 7

Step-by-step explanation:

Because this is a right triangle, one angle is a right angle (90°). All triangles have all three angle measures adding up to 180°, so the other two angles' measures add up to 90° (90 + 90 = 180).

Combine like terms of the angle measures.

6x + 9x = 15x

-3 + (-12) = -15

15x - 15

Because the sum of the measures of the two angles have to equal 90,

15x - 15 = 90

Add 15 from both sides.

15x = 105

Divide both sides by 15.

x = 7

To check, substitute 7 in both expressions.

6(7) - 3 = 39

9(7) - 12 = 51

39 + 51 + 90 (the measure of the right angle) = 180, so the value of x is 7.

Typically, its an offhand response from a parent to a child when someone has said something that hurt the childs feelings. After all, as long as theres no physical damage, then everything must be fine, right? Hurtful words are often treated as inconsequential. People assume they can be easily brushed aside and smoothed over with a flimsy apology on the part of the perpetrator. But the truth is, words can hurt in more ways than one and the effects often far outweigh any scrape or bruise. In todays world, our stories are no longer limited to simple word-of-mouth tales or even hard-bound books. Words are digital and far-reaching, passed around on websites, on social media, and in text messages. More often than not, the words we publish online are not really for the benefit of others, but for ourselves. Writer Gracy Olmstead says, in the world of internet and social media, another narrative has begun to reign supreme: namely, the self-narration. So, what happens when the words we use become more about self-gratification than genuinely helping or communicating with others? The result can be anything from shameless selfies to cyberbullying, and the effects are tangible. The Texas Education Code defines bullying as an act that exploits an imbalance of power and involves written or verbal expression. This has recently expanded to include digital forms of communication. These include sending vicious text messages, emails or instant messages, and spreading rumors or gossip by posting it to social networking sites. The sneaky thing about cyberbullying is that because its not physical, we underestimate its negative effects. With the anonymity and distance the internet provides, cyberbullies dont have to face the consequences of their actions, and often feel free to say whatever they want about others. History has proven that words can be just as potent weapons as if not more so than sticks and stones. During World War II, the Nazi regime employed propaganda to impress upon German civilians and soldiers that the Jews were not only subhuman but also dangerous enemies. The words of the German government became the defining narrative of an entire group of people. While this false propaganda seems a far cry from the problems facing teenagers today, they all demonstrate the impact of words. Novelist Chimamanda Ngozi Adichie put it simply when she said that the stories we tell are often about power. Power is the ability not just to tell the story of another person, but to make it the definitive story of that person, Adichie said. Perhaps the answer is not to fight to be heard, but rather to learn to listen. When we are empowered to tell our own stories or share our own points of view, our words can have positive, transformative effects. They can help people understand other experiences and see the world differently. Now that youve read about the effects words can have, what do you think? Has anyone ever said something about you that was hurtful or untrue? What did you do about it? How have you used words to solve a problem, bring people together, or share your own story? Why do words matter?
