If x = 3- 2 square root 2 , find the value of x square - 1 by x square.

you going to fail stop

step-by-step explanation:

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
