Question

How do you determine the number of possible solutions using the rule of law of sines given A=38°, B=63°, c=15?

Answer 1

C = 180 - B - A = 180 - 38 - 63 = 79 deg. Find a and b

`a/sin A = c/sin C -> a = (c.sin A)/sin C = (15(0.62))/0.98 = 9.49`

`b = (c.sin B)/sin C = ((15)(0.89))/0.98 = 13.62`

There is unique solution.
