Answer 1

Answer:

[tex]\sqrt{0.5}[/tex]

Step-by-step explanation:

cosx=adj/hyp

adj= [tex]\sqrt{2}[/tex]/2

hyp= r

cos(45)= ([tex]\sqrt{2}[/tex]/2)/r

[tex]\sqrt{2}[/tex]/2 = ([tex]\sqrt{2}[/tex]/2)/r

   multiply both sides by r

([tex]\sqrt{2}[/tex]/2)r = [tex]\sqrt{2}[/tex]/2

    divide both sides by [tex]\sqrt{2}[/tex]/2

r = 1

pythagorean theorem: [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

a = [tex]\sqrt{2}[/tex]/2

b = y

c = r = 1

[tex](\sqrt{2}/2)^{2}[/tex] + [tex]y^{2}[/tex] = [tex]1^{2}[/tex]

    [tex](\sqrt{2}/2)^{2}[/tex] = 2/4 = 0.5

0.5 + [tex]y^{2}[/tex] = 1

    subtract 0.5 from 1

[tex]y^{2}[/tex] = 0.5

[tex]\sqrt{y^{2}}[/tex] = [tex]\sqrt{0.5}[/tex]

y = [tex]\sqrt{0.5}[/tex]

If the diagonals of a quadrilateral are congruent, is the quadrilateral always a rectangle?

Answers

Answer:

Yes

Step-by-step explanation:

The only quadrilaterals with congruent diagonals are squares and rectangles and squares are technically rectangles so the answer is yes.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.

What is a quadrilateral?

The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral can be a square or a rectangle.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.

Answers

Answer:

A) x + 0

Step-by-step explanation:

In triangle ABC, the coordinates are: A(1, -1), B(1, -5) and C(4, -5)

In triangle A'B'C', the coordinates are: A(1, -5), B(1, 1) and C(4, 1)

Look at the x-coordinates in both the triangles remains the same because the triangles are reflected over x-axis, therefore, only the y-coordinate changes.

Therefore, the rule for x-coordinates = x + 0

Answer: A) x + 0

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

we can find angle C  b/c the angles of a triangle always add to 180 , soo

180= C + 81 +63.5

35.5 = C

now that we have angle C and we know the Hyp we can use sin to find side g

where g = Opp and Hpy = 13.8 for this question

Sin(35.5) = Opp / 13.8

13.8*Sin(35.5) = Opp

8.0137 = Opp

g = 8.0137

next they ask for the area of the biggest triangle  ABC ( there are two smaller ones when you use D )

we can use 1/2 * base * height , but we don't know the base yet, even thou we do know the height.  

we can solve for line segment CD and DB and then add them for the side a .. or the base of the biggest triangle sooo.. CD = adj

Cos(35.5) = Adj / 13.8

13.8*Cos(35.5) = Adj

11.234794 =Adj

now solve for DB using cos again but with the other smaller triangle where  Adj = DB now

Cos(63.5) = Adj / 8.9

8.9*Cos(63.5) = Adj

3.971160

add these two Adjs together to get the total  'a' side

15.205954

now plug in side a as the base and g as the height of our biggest triangle

Area = 1/2 * 15.205954 * 8.0137

Area = 60.9159

rounded to 2 sig figs

Area = 60.92   :)   hope you get an "A"    :P

Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2. Determine the new coordinates of point S', and state whether the dilation is an enlargement or a reduction

Answers

Given:

Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2.

To find:

The new coordinates of point S', and state whether the dilation is an enlargement or a reduction.

Solution:

If a figure is dilated by factor k with origin as center of dilation, then

[tex](x,y)\to (kx,ky)[/tex]

Where, 0<k<1 is reduction and k>1 is enlargement.

The figure is dilated by scale factor 2 which is greater than 1, so the dilation is an enlargement. The rule of dilation is:

[tex](x,y)\to (2x,2y)[/tex]

Using this rule, we get

[tex]S(4,-2)\to S'(2(4),2(-2))[/tex]

[tex]S(4,-2)\to S'(8,-4)[/tex]

Therefore, the new coordinates of point S' are (8,-4).

What is the Value of X in the triange

Answers

Answer:

x = 65

Step-by-step explanation:

The sum of the angles of a triangle add to 180

25+ 2x+25 = 180

Combine like terms

50+2x = 180

Subtract 50 from each side

2x = 180-50

2x =130

Divide by 2

2x/2 =130/2

x =65

It is 65 like the person above said

Answers

Answer:

16

Step-by-step explanation:

The formula for finding the length of a side of a right triangle is:

A^2 + B^2 = C^2 (c being the hypotenuse.)

We know what the length of the hypotenuse and one of the legs is, so we can solve by taking B^2 (the leg measuring 12) and subtracting it from C^2 (the hypotenuse) and then finding the square root of C^2.

20^2 - 12^2 = 256

or in simpler terms

20^2 - 144 = 256

Then, if we find the square root of 256 we get 16. We can check our work by substituting it back into the equation

16^2 + 12^2 = 20^2

or in simpler terms

256 + 144 = 400

So the length of the missing leg is 16. I hope this helps :)

Answer:

C. 16

Step-by-step explanation:

In order to find one side of a right triangle, given two sides, you can use the Pythagorean theorem: [tex]A^2+B^2=C^2[/tex]

We already have the values of one of the bases (12) and the hypotenuse (20), so we are looking for the second base. So, we have the values of B and C, and we need to find A.

To find A, put the values you already have into the formula as follows:

[tex]A^2+12^2=20^2[/tex]

Next, square each value:

[tex]A^2+144=400[/tex]

Subtract 144 from 400 to simplify the equation.

[tex]A^2=256[/tex]

And finally, find the square root of 256 to find A.

[tex]A=16[/tex]

Final answer:

C. 16

Answers

Answer:

Circumference = 6.92π

or

21.75 cm

Step-by-step explanation:

Area of Circle = π × radius²

Area of Circle = 12π cm

π × radius² = 12π

radius² = 12

radius = √12

radius = 3.46

Circumference = 2 × π × radius

Circumference = 2 × π × 3.46

Circumference = 6.92π

First, you would use the distributive property to multiply -7 into the parenthesis. Then you’d have 8x-3.5x-49=14 Then you add 49 to both sides to combine like terms and get 8x-3.5x=63 Next you would combine like terms on the left side by subtracting 3.5x from 8x and end up with 4.5x=63 Then to get x by itself you would divide by 4.5 on both sides and end up with X=14 being your answer.
