A 15 meter long cable is used to support a telephone pole, holding it perpendicular to the ground. If the cable forms a 38° angle with the ground, how high up the pole should the cable be attached?

Answer:

9.2 m

Step-by-step explanation:

Given that the length of the rope = 15 m

Angle it makes with the ground = 38°

The height of the Pole = x

We know that;

Sin 38° = x/15

Therefore;

x = 15 sin 38°

x= 9.2 m

Hence, it should be attached at 9.2 m
