Answer:

$\boxed{h=60.1\ ft }$

Step-by-step explanation:

<u>Right Triangles </u>

They have a right angle (90°) and a longer side called the hypotenuse opposite to the right angle. The legs and the hyponetuse form two angles that must sum 90°, and they comply:

$\displaystyle sin\ \alpha=\frac {opp-leg}{hypotenuse}$

Where opp-leg is the opposite leg to $\alpha.$

The rope from the top of a tree house is 85-foot long. It's the hypotenuse (L) of the triangle it forms with the ground and the tree. The angle of 45° is opposite to the height of the tree (h).

$\displaystyle sin\ \alpha=\frac {h}{L}$
