Question

In the triangle below, b=_____. If necessary, round your answer to two decimal places.

Answer 1

law of sines for this one

Answer 2

I got that sinB= 110.4, I just don't know what to do after that.

Answer 3

\[m \angle B = 100.4\]

Answer 4

law of sines:\[{\sin(A) \over a} = {\sin B \over b}\]

Answer 5

I did it again with that formula and I got -10.88, which I assume is incorrect since it is negative.

Answer 6

\[b= a \times {\sin B \over \sin A}\\ = 25 \times {\sin 110.4° \over \sin 38°}\]

Answer 7

you need to use your calculator in degree mode

Answer 8

Alright, I got 39.94. Is this correct?

Answer 9

38.06

Answer 10

Thank you!
