Ответ:
Length = 42.7 feet
Step-by-step explanation:
By considering it as right triangle we use trigonometric ratios to find the length of the ladder.
Given angle of elevation and adjacent side. We have to find the hypotenuse.
Trigonometric ratios
To find length of ladder ( or hypotenuse ) :
Therefore, length of the ladder = 42.7 feet.
