Since you have two angles that measure 45 degrees. Those 2 equal 90 degrees altogether. Since a triangle measures 180 degrees, you take 180-90 because you already have 2 angles and are trying to find the last one. Then this makes the last angle 90 degrees.
4x+8 = 32, 4x = 24, x = 6

Answer:

(f-g)(-4) = -151
Step-by-step explanation:
To find f-g(x) we subtract the common terms. So


(f-g)(x)

(f-g)(-4)

We replace x by -4

(f-g)(-4) = -151
