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 .

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

can you put the picture up?
