Question

What is the value of cos B as a simplified fraction. (Enter answer as x/y to enter the fraction).

Answer 1

Cos of B = 36 / 38.884

Explanation:

To find the cos of b you need the hypotenuse

(a)^2 + (b)^2 = (c)2

(36)^2 + (15)^2 = 1521

1521 squared is 38.884

Hypotenuse side goes on bottom and adjacent side on top

Cos of B = 36 / 38.884
