To estimate the height of a totem pole, Jorge uses a small square of plastic. He holds the square up to his eyes and walks backw

Ghella [55]

The height of the pole is 6.50 meters

<h3>How to calculate the height?</h3>

To calculate the height of the pole, we will use of the following equivalent ratios.

By Pythagoras theorem, we have:

$x ^2 = 2^2 + 3^2\\\\x ^2 = 4 + 9\\\\x = \sqrt{13}$

So, we have:

$h = \dfrac{\sqrt{13}^2 }{2} \\\\h = \dfrac{13}{2}\\\\h = 6.5$

Hence, the height of the pole is 6.50 meters
