Question

LOOK AT CAPTURE AND ASNWER 100 POINTS

Answer 1

132

Explanation:

ANGLE A = ANGLE B

(INTERIOR ALTERNATE ANGLES)

5x - 18 = 3x + 42

2x = 60

x = 30

angle a = 150 - 18

= 132

Answer 2

132 degrees

Explanation:

Looking at angle A and angle B, they are alternate interior angles. That means they are congruent to one another. Knowing that, we can set up an equation A=B

We can now fill A and B with their given equations

5x-18=3x+42

Now we solve

2x=60

x=30

Now that we know x is 30, we can replace it in the equation for A

5x-18

5(30)-18

150-18

132 degrees
