b: 8/15
c: 15/17
d: 17/15
e: 17/8

Step-by-step explanation:

In the given image the triangle is right angled triangle.

Given data: Hypotenuse = 34, Base = 30, Opposite side = 16

The formula for cos r is

Cos r =

Substitute the value of base and hypotenuse in the formula

Cos r =  

         =

Cos r =  (cancel the common term)

Therefore, the value of cos r is .
