Question

What is the value of the cosine of v to the nearest hundredth.

Answer 1

First, draw the triangle as follows to illustrate the parts of the given triangle:

Since the triangle is right, we may use the trigonometric identity to find cos V. The computation for the cos V is as follows:

`\cos V=\frac{adjacent\text{ side}}{hypothenuse}`

Substitute the values of the given such that the hypothenuse is the longest side of the triangle, UV.

`\cos V=(WV)/(VU)=(40)/(41)\approx0.98`
