Answer:

cosC = 30/50

Explanation:

Before you find cosC, you should know that:

tangent = opposite side/adjacent side

sine = opposite side/hypotenuse

cosine = adjacent side/hypotenuse

You should also know that trigonometric ratios work for only right triangles.

If cosine = adjacent side/hypotenuse, then:

cosC = 30/50

cosC = 0.6

If rounding to the nearest four decimals, it should be 0.6000.
