Question

Can someone help me with this problem? Plzzzz

Answer 1

mAngle A= 132 degrees

Explanation:

a = 5x-18. b= 3x+42

a=b because they are alternate interior

5x-18=3x+42

combine like terms

SUbtract 3x from both sides and add 18 to both sides

2x=60

divide by 2

x = 30

Now plug in 30

5(30)=150

150-18=132
