Question

If A = 50 degrees, B = 62 degrees, and a = 4, find b.

Round to the nearest tenth.​

Answer 1

Answer: 4.6

=================================================

Work Shown:

Use the law of sines

b/sin(B) = a/sin(A)

b/sin(62) = 4/sin(50)

b = sin(62)*4/sin(50)

b = 4.61042489526572

b = 4.6

Make sure your calculator is in degree mode.
