Find The Measure Of Angle A

Answers

Answer 1

Answer:

30

Step-by-step explanation:

Right angle = 90 degrees

180-90 = 90, hence the right side of the equation.

x+37+x+67 = 90

2x + 104 = 90

2x = -14

x = -7

Plug in x.

-7+37 = 30 (angle a)

Angle a  = 30

Answer 2

Answer:

angle A = 30 degrees

Step-by-step explanation:

*All triangles have an interior angle that adds up to 180 degrees

The triangle is the picture is a right triangle so one of the angles is 90 degrees.

First, we must figure out what "x" is:

⇒ 180 = 90 + x + 37 + x + 67

Combine like terms:

⇒ 180 = 2x + 194

Subtract 231 from both sides:

⇒ 180 - 194 = 2x + 149- 194

⇒ -14 = 2x

The divide both sides by 2:

⇒ [tex]\frac{-14}{2} + \frac{2x}{2}[/tex]

⇒ -7 = x

Now, we can figure out what angle A is by taking the equation "x + 37" and subtituting x by -7:

⇒ x + 37

⇒ -7 + 37

⇒ 30

To check out answers, take all of the eqautions in the picture and subtitute x by -7, (remember that it must add up to 180):

⇒ 90 + x + 37 + x + 67 = 180

⇒ 90 + (-7) + 37 + (-7) + 67 = 180

⇒ 180 = 180

x=1, y=-2

Step-by-step explanation:

2x-3y=8 (1)                            

4x+3y=-2 (2)

From (1):

2x=8+3y

x=4+1.5y (3)

Subst (3) into (2)

4(4+1.5y)+3y=-2

16+6y+3y=-2

16+9y=-2

9y=-2-16

9y=-18

y=-2

subst y=2 in to (3)

x=4+(1.5*-2)

x=4-3

x=1

Lets us start with finding the inner angles of the triangle. The bottom right angle shall be 70 degrees as it is opposite. The 100 degrees shall add together to make 200. 360-200 = 160. 160 / 2 = 80. So, Now we know bottom left angle (80) and bottom right (70). 80 + 70 = 150. In a triangle, angles add to 180 so 180 - 150 = 30. 30 = 2x which means that x = 15

What is the value of y in the figure below?
(7y + 27)
(15x - 5)
125°

Answers

Answer:

Simplifying

(7y + 27) + (15x + -5) = 125

Reorder the terms:

(27 + 7y) + (15x + -5) = 125

Remove parenthesis around (27 + 7y)

27 + 7y + (15x + -5) = 125

Reorder the terms:

27 + 7y + (-5 + 15x) = 125

Remove parenthesis around (-5 + 15x)

27 + 7y + -5 + 15x = 125

Reorder the terms:

27 + -5 + 15x + 7y = 125

Combine like terms: 27 + -5 = 22

22 + 15x + 7y = 125

Solving

22 + 15x + 7y = 125

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-22' to each side of the equation.

22 + 15x + -22 + 7y = 125 + -22

Reorder the terms:

22 + -22 + 15x + 7y = 125 + -22

Combine like terms: 22 + -22 = 0

0 + 15x + 7y = 125 + -22

15x + 7y = 125 + -22

Combine like terms: 125 + -22 = 103

15x + 7y = 103

Add '-7y' to each side of the equation.

15x + 7y + -7y = 103 + -7y

Combine like terms: 7y + -7y = 0

15x + 0 = 103 + -7y

15x = 103 + -7y

Divide each side by '15'.

x = 6.866666667 + -0.4666666667y

Find the roots/zeroes of the following polynomial

x^2−19=6

Answers

Answer:

x=5 and x=-5

Step-by-step explanation:

1. first you would subtract 6 from both sides to set the equation = to zero.  

2. The equation would then be x^2-25=0.

3. that is a difference of two squares polynomial. So when you factor it, it is (x+5)(x-5)=0

4. by the zero product property, the roots are 5 and -5.

Scanti Lee Clad has 15 short shorts and 11 sleeveless blouses. In how many different ways could she select a shorts-blouse combination?

Answers

Answer: 165 different combinations.

Step-by-step explanation:

Here we first need to identify the "selections", and then the number of options for each selection.

Here we have two selections, shorts, and sleeveless blouses.

For shorts, we have 15 options.

For sleeveless blouses, we have 11 options.

The total number of combinations will be equal to the product between the numbers of options for each selection, then the total number of combinations is:

C = 11*15 = 165

We know that,

An expression is a combination of numbers, variables, and operations that can be evaluated to produce a value.

It can represent a mathematical relationship or a computation.

To simplify the expression 5d - 7 - d + 4, we can combine like terms.

First, let's group the terms with the variable "d" together:

(5d - d) - 7 + 4

Simplifying within the parentheses:

4d - 7 + 4

Combining the constants:

4d - 3

Therefore, the simplified expression is 4d - 3.
