The correct answer is choice C
Answer:
116
Step-by-step explanation:
Given shape has 6 angles and the sum of interior angles for this shape is calculated as following:
180*(6-2) = 720 now to find x we need to find the sum of given angles first:
144 + 163 + 50 + 131 + 126 x = 720
614 + x = 720 subtract 614 from both sides
x = 116
Answer:
<h2>x = -3</h2>
Step-by-step explanation:
<u>15 - 7x </u>= 9
4
-7x = 9(4) - 15
x = 21/-7
x = -3
proof:
<u>15 - 7(-3) </u>= 9
