Question

The picture below shows a pole and its shadow:

A pole is shown with a right triangle side. The right triangle has hypotenuse 221 cm and base 21 cm.

What is the height of the pole?

121 centimeters
220 centimeters
225 centimeters

Answer 1

the height of the pole is 220 centimeters

Explanation:

The computation of the height of the pole is shown below

Here we applied the pythagoras theorem

Given that

Hypotenuse = 221 = c

And, base = 21 cm = b

a^2 + b^2 = c^2

So, the height is

= 21^2 cm - 221 cm

= 441 cm - 221 cm

= 220 cm

Hence, the height of the pole is 220 centimeters
