Step-by-step explanation:
a^2 + 2(b - 6) - 17. a = -7 b = 2
= (-7)^2 - 2(2 - 6) - 17
= 49 - 4 + 12 - 17
= 40
That would be 30 it took me a rlly long time sorry hope it helps
The angles must add up to 360 degrees, so we can set the sum of the interior angles equal to 360 and solve for x.
106 + 94 + 135 + x + (x + 5) = 360
Combine like terms:
340 + 2x = 360
2x = 20
x = 10
