Functions h and k are Inverse functions, and both are defined for all real numbers. Using this relationship, what is the value of each function composition?
(h o k)(3) =
(koh)(-40) =

That little box would be 90 degrees. a triangle should be 180 degrees. 90 + 15= 105. 180-105=75. your answer would be 75 degrees but since you asked for the nearest tenth, it would be 80 degrees.
