Answer:
Step-by-step explanation:
The sum of the interior angles of a triangle is equal to 180 degrees, and each side of a straight line is equal to 180 degrees. Therefore, the exterior angle labelled 
must be equal to the sum of the two angles marked 
and 
:
Thus, the missing angle is .
F(x)= 12 / (4x+2 )
f(-1) mean to replace x by (-1)
so, f(-1) = 12 /(-4+2)
f(-1)= 12/-2
f(-1) = -6
