Which link between two elements could you remove from the relation so that it becomes a function? A. 2 and d or 5 and d

B. 3 and b or 3 and e

C. 3 and b or 4 and b

D. 2 and d or 3 and b

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
