b=24 c=29 B=40deg

**Reiny**, Tuesday, July 2, 2013 at 12:02pmI get two.

make a sketch

Using the Sine Law, you will get

sinC = 29sin40/24 = .776...

so C = appr 51 degrees or 180-51 = 129 degrees

(since the sine is positive in I or II)

You will be able to draw a second triangle with B = 40, C = 129 and A = 11 degrees

This is called the ambiguous case.
