Question

If BFD and AFC are right angles and

m CFD = 72°, what is the value of x?
18
36
108
72

Answer 1

72

Explanation:

If BFD is a right angle and it gives you CFD that means that you do 90 - 72 to find CFB cause it 90 all togther

CFB = 18 deg

now it also tells us CFA is a 90 deg angle so we do the same thing

90 - 18 = 72
