When i stand 30 feet away from a tree at home, the angle of elevation to the top of the tree is 50◦ and the angle of depression
geniusboy [140]
  1. You can use the information given in the problem above to draw the diagram of the situation, as you can see in the figure attached.
  2. You must calculate the heights h1 and h2 and sum them to find the total height Ht of the tree, as below:

Tan(50)=\frac{h1}{30} \\ h1=35.75ft

Tan(10)=\frac{h2}{30} \\ h2=5.28ft

Ht=h1+h2\\ Ht=41 ft

The answer is: 41 ft
