Question

Use the pythagorean formula to find X the triangle has 20 and 16 and X what is x​

Answer 1

Answer: 12

Step-by-step explanation:

Using Phytagorean theorem

`r^(2) = \sqrt{} y^(2) +x^(2)`

given: r=20 and y=16

`20^(2) =\sqrt16^(2) +x^(2) \\400=\sqrt{256+ x^(2) \\`

move x to the other side (when x is moving to the other side the sign change)

x²= √400-256 subtract

x= √144 take the square root

x= 12
