Question

In angle BCD, the measure of

Answer 1

To solve this problem, you can use the following diagram as a reference:

To determine the cosine of angle B, recall that in a right triangle:

`cos\alpha=\frac{adjacent\text{ leg}}{hypotenuse}.`

Therefore:

`cosB=(36)/(85).`

Rounding the solution to the nearest hundredth, you get:

`cosB\approx0.42`

Answer:

`0.42`
