Question

A man at ground level measures the angle of elevation to the top of the building to

be 87°. If at this point, he is 20 meters away from the building, what is the height of
the building?​

Answer 1

The bulding is 381,623 meters high.

Explanation:

To dertermine the height of the bulding I would use tanα = rectangulair side / closest rectangulair side.

19,08 = the height/ 20m.

<=> 19,08.20m= the height = 381,623 m
