Question

A triangle ABC has two side lengths of 28 ft. and 24 ft. If angle C is 91°, what's the measurement of angle B?

Answer 1

B = 58.9

Explanation:

We are given that a triangle ABC has two side lengths of 28 ft. and 24 ft. with angle C measuring 91°. We are to find the measure of angle B.

AB = 28 ft

AC = 24 ft

For this, we will use the sine formula:

`(sin B)/(24) = (sin91)/(28)`

`sin B = (sin91 * 24)/(28)`

`sin B = 0 . 8 5 7`

`B = sin' 0 . 8 5 7`

B = 58.9
