Answer:

Explanation:

Givens

You have the hypotenuse: 13

You seek the adjacent side: x

You have the angle enclosing the 2: 47 degrees.

The relationship is the Cosine

Solution

Cos(47) = opposite / hypotenuse

Cos(47) = 0.6820 From your calculator

Cos(47) = x / 13 Multiply both sides by 13

13*cos(47) = x

x=8.866
