Question

a ladder 6 metres long leans against a building the angle formed by the lander and the ground 66 degree how far from the building is the foot of the ladder

Answer 1

It is a right angle triangle with hypotenuse=6m and the angle between the base and the hypotenuse is 66°

So,

Cos66°=x/6

Value of cos66°=0.406

0.406=x/6

x=2.436m

So the distance between the foot of ladder and the building is 2.436m

Answer 2

Answer:

2.436

Step-by-step explanation:

cos 66 in the table is 0.406

so 0.406=x/6

x=0.406×6

x=2.436
