Question

The angle of elevation of top of a ladder leaning against a wall is 60o and the foot of

the ladder is 9 m away from the wall. Find the length of the ladder.​

Answer 1

Answer:

length of the ladder = 18m

Step-by-step explanation:

Hypotenuse = ladder, distance from wall = base and, wall = perpendicular

cos = adjacent side / hypotenuse

cos 60 =1/2

1/2 = 9 / hypotenuse (ladder)

length of ladder = 18m
