Question

A ladder is leaning against the side of a building. The bottom of the ladder makes an angle of 73 degrees with the ground and is 0.9 m from the bottom of the building. Determine the length of the ladder.

you are looking for the hypotenuse, and have adjacent. So, use COS.

cos(73)=0.9/x

simplified 0.9/cos(73)

calculate.
