I think it's a 30 60 90 special triangle to find x but I need help!

The value of x is .

Solution:

Given image is a right triangle.

Hypotenuse = 30

Part 1 = 20

Part 2 = Hypotenuse - Part 1

          = 30 - 20

Part 2 = 10

Leg = x

Leg rule of geometric mean theorem:

Do cross multiplication.

Taking square root on both sides, we get

The value of x is .

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16
