What is the measure of ∠PCB? 75 degrees

18 degrees

33 degrees

144 degrees

3rd Option, 33° = ∠PCB

Step-by-step 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!

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

2425
