Answer:
x=-85
Step-by-step explanation:
Y=6 when x=18, find y when x=-12
so 6/18 = y/-12
cross multiplication
(6)(-12) = (18)(y)
-72 = 18y
divide both sides by 18
-4 = y

Mid-point of BC, M=(2+(-5),8+5,-5+(-8))/2=(-1.5, 6.5, -6.5)
Vector from A to M = M-A=<(-1.5,6.5,-6.5)-(4,3,-4)>=<-11/2,7/2,-5/2>
The correct answer is (C)!
Triangle IJK is an iscoceles triangle. Since the interior angle of a regular pentagon is 108°, Angle JIK = 36°.
Hence, Angle HIK = 108° - 36° = 72°.
