Imagine that you are standing on the ground 15 feet away from a flagpole. if the top of the flag is 25 feet high, which equation represents the angle θ your feet make with the top of the flag?

tan theta = 25/12, so
theta = tan^-1 (25/15)

Answer: Hence, the angle of elevation with the top of the flag is 59° and

And the equation would be
\theta=\tan^(-1)((AB)/(BC))

Explanation:

Since we have given that

Height of top of the flag = 25 feet

Distance of the base of flagpole from the person standing on the ground = 15 feet

We need to find the angle of elevation θ :

Consider ΔABC,


\tan \theta=(AB)/(BC)\\\\\tan\theta=(25)/(15)\\\\\tan \theta=1.67\\\\\theta=\tan^(-1)(1.67)\\\\\theta=59^\circ

Hence, the angle of elevation with the top of the flag is 59°.

And the equation would be


\theta=\tan^(-1)((AB)/(BC))
