The transformer (grey box) on this power line is how far above the ground?
Round to the nearest tenth.

The transformer is 27.5 ft above the ground.

Solution:

The given image is like a triangle.

Angle 'L' represents the triangle is right triangle.

Use Pythagoras theorem to find the answer.

Base of the triangle = 12 ft

Hypotenuse of the triangle = 30 ft

Height of the triangle = x

Using Pythagoras theorem,

Subtract 144  on both sides of the equation.

Taking square root on both sides.

Hence the transformer is 27.5 ft above the ground.
