1) Answer: x = 9
Step-by-step explanation:
Same Side Interior Angles are supplementary
15 + 5x + 14x - 6 = 180
19x + 9 = 180
19x = 171
x = 9
***************************************************************
2) Answer: x = 9
Step-by-step explanation:
Corresponding Angles are congruent
13x - 7 = 11x + 11
2x = 18
x = 9
***************************************************************
3) Answer: x = -10
Step-by-step explanation:
Alternating Interior Angles are congruent
90 = x + 100
-10 = x
***************************************************************
3) Answer: x = 7
Step-by-step explanation:
Alternating Exterior Angles are congruent
17x + 1 = 120
17x = 119
x = 7
