Question

2. Find the measure of b, given m∠A = 38°, m∠B = 74°, and a = 31. (1 point)

Answer 1

Use the sine formula: \(\frac{sin(A)}{31} = \frac{sin(B)}{b}\).

(Forgot if it's in the correct place - if not just swap the sines)

Answer 2

i don't really know how to use them

Answer 3

@artem151 Might need to go back and revise more then, but here's a dumbed-down version of it:



In here, \(\frac{sin(A)}{a} = \frac{sin(b)}{b} = \frac{sin(C)}{c}\).

Answer 4

so the answer would be 48.4
