Answer:
(x+1)²= 49, the answer is B
Step-by-step explanation:
x² + 2x = 48
x² + 2x + (2/2)² - (2/2)²= 48 --[what we are trying to do is to complete a square by adding (2/2)² - (2/2)²]
(x+1)²= 49, the answer is B
Supplementary means they add up to 180
angle 1 = x
angle 2 = x + 166
so x + x + 166 = 180
2x = 14
x = 7
so angle 1 = 7 angle 2 = x + 166 = 173
