Question

A right triangle is shown below which ratio gives the cosine of angle b?

Answer 1

The cosine property of an angle is:

`\cos (angle)\text{ = }\frac{\text{adjacent leg}}{\text{hypotenuse}}`

In the case of the B angle, it will be:

`\cos (B)\text{ = }(a)/(c)`

Therefore the answer is the letter D, a/c.
