Question

Robert is lying on the ground, looking at the top of a flagpole. The angle of elevation to the top of the flagpole is 25 degrees. What is the height of the flagpole if the distance from his eyes at the ground to the base of the flagpole is 200ft?

Answer 1

Hi Roxanana M

Draw yourself a picture, your description sounds like you have Right Triangle with a base length 200 ft with an angle of elevation of 25 degrees. 200 ft is the length of the base, the adjacent side, the height, h, is the side opposite the 25 degree angle.

Since the Tangent in a Right Triangle is OPP/ADJ

Tan25° = h/200

(tan25°)*200 =h

Can you finish the calculation from here

Please give it a try.
