The angle looking up at the sun is 70°. a flagpole casts a shadow of 15 ft. draw a diagram and find the height of the flagpole
a) 41.2 ft.
b) 14.1 ft
c) 5.5 ft

The length of the flagpole be 41.2 ft .

Option (A) is correct .

Step-by-step explanation:

As given

The angle looking up at the sun is 70°.

A flagpole casts a shadow of 15 ft .

Now by using the trignometric identity .

BC = 15 ft

tan 70° = 2.75 (Approx)

AB = 2.75 × 15

     = 41.2 ft

Therefore the length of the flagpole be 41.2 ft .

Option (A) is correct .
