Question

A 15ft ladder is leaning up against a wall. The top of the ladder makes a 12° with the wall, how far is the base of the ladder from the wall?​

Answer 1

Explanation:

`the \: length \: of \: the \: ladder \: becomes \: the \: hypotenuse \:`

`the \: base \: becomes \\ = \sin( \alpha ) * hypotenuse \\ = \sin(12) * 15 \\ = 3.119ft`
