Use the Law of Sines to solve the following triangle.

Question

c = 10.2 in, A = 45.1° B = 75.8°

Answer 1

first we obtain the value of C angle which becomes = 180 - 45.1 - 75.8 = 59.1 degrees.

Then using the sine law we can obtain the lengths of the other sides.

c/sin C = b/sin B = a/sin A

so we obtain:

b=11.40 inches

a= 8.42 inches
