Question

Kurt leans a 20-ft long ladder against the side of his house. The ladder reaches to a height of 18.9 feet up the side of the house. What is the angle of elevation of the ladder to the nearest tenth of a degree?

Answer 1

70.9°

Explanation:

Hypotenuse = 20

Leg = 18.9

We will need to use Sin to find the angle since the given leg is opposite of the angle of elevation.

`sin^(-1) ( (Leg)/(Hypotenuse) )`

`sin^(-1) ( (18.9)/(20) ) = 70.9`
