Question

A 20ft ladder leans against a building and it touches the building 18ft above the ground. What is the angle of elevation that the ladder makes with the ground

Answer 1

The angle is [/tex]64.1581^{\circ}[/tex]

Explanation:

You can figure this out using the sine function:

`\sin(v)=(18 ft)/(20 ft) \\= (9)/(10)\\ v= \arcsin((9)/(10) )\\= 64.1581^(\circ)`
