Question

A ladder leaning against a wall makes a 60 angle with the ground if the lenght of the ladder is 41 m then find the distance if the foot of the ladder from the wall

Answer 1

cos 60 = x÷41m
0.5 = × ÷ 41m
0.5 × 41m = x
x = 20.5 m

Answer 2

A ladder leaning against a wall makes a 60 angle with the ground if the lenght of the ladder is 41 m then find the distance if the foot of the ladder from the wall,cos60
x=20.5
