Answer:
A. 17°
Step-by-step explanation:
We know that point r is 73° and point p is a right angle (90°) all triangles equal 180° on the inside. If you add 73 and 90, you get 163. Then subtract 163 from 180 to get 17.
F(-4)= 9*3^(-4)=9/(3^4)=1/9
It is 2.4 because 16 goes twice and the remainder is 4
