Question

A ladder 10 m long is leaning against a vertical wall. It makes an angle of 60° with the ground. How far is the foot of the ladder from the wall?

Answer 1

When we represent this as a triangle, the hypytenues is 10m. We need to find the adjacent dist to the angle 60°. 
Cos 60°= 1/2= adj/hyp
                1/2= adj/10
                 10= 2adj
                adj= 5m
∴The foot of the ladder is 5m far from the wall!

Answer 2

Answer:

5 m

Step-by-step explanation:

When we represent this as a triangle , the hypotenuse is 10 m . we need to find the adjacent dist to the angle 60° . The foot of ladder is 5 m far from wall

m = Meter
