What does the angle-angle criterion tell you about the relationship between two triangles? use the drop-down menus to explain your answer.

Similarity. In two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar

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
