all shapes with 4 angles are 360 degrees
100+96= 196
360-196= 164
c+d=164
80+84=164
D is 84
C is 80
Answer:
FC = 27, QC = 18
Step-by-step explanation:
The centroid Q is
the way along CF , therefore, QF is half as long as CQ
Given FQ = 9, then
QC = 2 × 9 = 18
FC = FQ + QC = 9 + 18 = 27
You have to add all the numbers then leave one and subtract it
