Question

What is the value of X in the figure at right? You gonna assume that the trunk and a fallen tree make a right triangle with the ground

Answer 1

x = 16

Explanation:

we use the Pythagorean theorem

20² - 12² = x²

400 - 144 = x²

256 = x²

x = √256

x = 16

triple of Pythagoras = 3.4 and5

3*4=12

4*4=16

5*4=20
