Use the Law of Sines to solve the triangle A 63 degree a 9

Use the Law of Sines to solve the triangle. A = 63 degree, a = 9, c = 10 Use the Law of Sines to solve the triangle. B = degree C = degree C = degree

Solution

a/sinA = b/sinB = c/sinC

9/sin63 = 10/sinC => C = 81.89^o or C = 98.11^o

when C = 81.89^o  

B = 180 -63 - 81.89 = 35.11

b = asinB/sinA = 9 x sin35.11/sin63 = 5.81

when C = 98.11^o  

B = 180 -63 - 98.11 = 18.89

b = asinB/sinA = 9 x sin18.89/sin63 = 3.27
