Question

STUDY GUIDE HELP Use the Law of Sines to find the missing side of the triangle.Find the measure of b, given m∠A = 38°, m∠B = 74°, and a = 31.

Answer 1

use sinA/a=sinB/b to find b

Answer 2

180-38-74 gives you angle C recall all three angles must add up to 180 degrees

Answer 3

use sinA/a=sinC/c to find c

Answer 4

@precal so would it be sin(38)/a?

Answer 5

=sin(74)/a?
