Given:
16-ft ladder
Angle of 73 with the ground
First, let us sketch the problem for us to underdtand what do we need to do in order to solve this problem.
Now, we can rewrite the given as:
hypotenuse = 16
angle = 73
Find for the opposite side h.
For us to solve this, we will use the following equation

Plugging in the given data,

*Multiply both sides by 16


Therefore, the final answer would be 15.30 ft.
