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,

$\text{Base} $^{2}+$ Height $^{2}=$ Hypotenuse $^{2}$$

12^2+x^2=30^2

144+x^2=900

Subtract 144 on both sides of the equation.

x^2=900-144

x^2=756

Taking square root on both sides.

x=27.5

Hence the transformer is 27.5 ft above the ground.
