(sorry i'm not typing it again just read the other two explanation sections i just typed it'll be the same.)
Answer from: Quest
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
