Sorry just coming for the points
We know that
mGJI+117.33°=360° (full circle)
so
mGJI=360°-117.33°-----> 242.67°
the answer is
242.67°
The answer is x=42.8+- (plus or minus) 12
So he should either have $30.80 or $44.80 left
X^2+4x-12
x^2+6x-2x-12
x(x+6)-2(x+6)
(x-2)(x+6)
So, B is the answer
4^2+b^2=8^2
16+b^2=64
-16. -16
b^2= 48
Sq root each side
b= sq rt 16 sq rt 3
b= 4 sq rt 3
