Set the angles equal because they are vertical angles
150=5m
30=m (divide both sides by 5)
<u>Answer</u>:
x = 5
<u>Explanation</u>:
If the angle are parallel:
step 1:
21x + 7 = 22x + 2
21x - 22x = 2 -7
-x = -5
x = 5
finding upper angle, then when both lies on straight line equals to 180°
step 2:
180 = (180 - 22x - 2 ) + 21x + 7
180 = 180 - 2 + 7 - 22x + 21x
180 = -x 185
-5 = -x
x = 5
