Recall all interior angles in a triangle add up to 180°, therefore

\bf \stackrel{A}{x+40}~~+~~\stackrel{B}{2x-5}~~+~~\stackrel{C}{3x-17}~~=~~180
\\\\\\
6x+18=180\implies 6x=162\implies x=\cfrac{162}{6}

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
