B)
Because if you find the degrees for angle 1 you get:
180⁰ - 45⁰- 39⁰ = 96⁰ <- angle 1
The triangle in the center has 3 angles, and those 3 angles will equal 180⁰
So, 180⁰ - 96⁰ = 84⁰

Answer:
(h o k)(3) = 3
(k o h)(-4b) = -4b
Step-by-step explanation:
If f(x) and g(x) are inverses, then (f o g)(x) = (g o f)(x) = x
(h o k)(3) = 3
(k o h)(-4b) = -4b
