If cos f° = 4/9 and the measure of XW is 16 units, what is the measure of XY

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

the answer is actually 18%
