Question

For the following right triangle, find the side length x. Round your answer to the nearest hundredth.X10Х20

Answer 1

In order to calculate the the side length x we would have to use the pythagorean theorem.

pythagorean theorem

$a^2+b^2=c^2$

According to the picture, the a side is 10, the b is x, and the c side is 20.

Therefore, using pythagorean theorem we would be able to calculate the value of x.

So:

if a^2 + b^2=c^2

10^2+x^2=20^2

x^2=400-100

x=√300

x=17.3

The side length of x would be 17.3
