Ive tried to work these problems but am unsure of how exactly to get the correct answer.

a man jumps out of a plane at 4250 feet directly over his target and falls 82 degress to the ground. How far did he miss his target?

A tree cast a shadow of 12 feet and the distance from the end of the shadow to the top of the tree is 13 feet. How tall is the tree?

What is the answer and how did you work this problem out step by step.
