Answer:


\theta=13.5^(\circ)

Explanation:

Given that,

The height of a flagpole, h = 12 feet

the height of the shadow, b = 50 feet

We need to find the angle of elevation of the sun. Let it is be θ. Using trigonometry to find it.


\tan\theta=(P)/(B)\\\\\tan\theta=(12)/(50)\\\\\theta=13.49^(\circ)\\\\or\\\theta=13.5^(\circ)

So, the angle of elevation to the sun is equal to
13.5^(\circ).
