Question

The base of a ladder is 10 feet away from the bottom of a building’s wall. if the ladder makes a 35 ◦ angle with the ground, find the length of the ladder to the nearest tenth of a foot.

determine how high the ladder can reach up
the wall of the building.

Answer 1

Explanation:

let the length of ladder=l

`(10)/(l) =cos 35\\l=10 sec 35 \approx 12 .2 ~ft\\(h)/(10) =tan 35\\h=10 tan 35 \approx 7.00 ~ft`

where h is the height.
