Question

What is the measure of ∠PCB?

75 degrees

18 degrees

33 degrees

144 degrees

Answer 1

3rd Option, 33° = ∠PCB

Explanation:

First find the measure of ∠CPB;

∠CPB = 180 - 105

∠CPB = 75

Now we can find the measure of ∠PCB;

180 - (Angle 1 + Angle 2)

180 - (75 + 72)

33 = ∠PCB

Hope this helps!
