In triangle WXY, the measure of angle Y=90 degrees, XW=89, WY=80, and YX=39. What ratio represents the cosine of angle X?

Step-by-step explanation:

Given: In triangle WXY,

∠Y = 90°, XW = 89 units, WY = 80 units and YX = 39 units.

According to trigonometry ,

Cosine of A

From the figure below,

Hence, required ratio =
