Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Find the cosine of ∠K.

Write your answer as an integer or as a decimal rounded to the nearest hundredth.

cos(K) =

Answer 1

Explanation:

Triangle IJK is a right angle triangle.

From the given right angle triangle

JK represents the hypotenuse of the right angle triangle.

With ∠K as the reference angle,

IK represents the adjacent side of the right angle triangle.

IJ represents the opposite side of the right angle triangle.

To determine Cos K, we would apply trigonometric ratio

Cos θ = adjacent side/hypotenuse. Therefore,

Cos K = 36/85

Cos K = 0.4235

Rounding up to the nearest hundredth,

Cos K = 0.42
