Find the area of the triangle. b=125 c=162 <B=40 (b and c are the sides) (<B is the angle)

  Use the law of sines to solve for <C. (sin <C)/c = (sin <B)/b Use <A + <B + <C = 180 to solve for <A Uze the law of sines to solve for a. The triangle area is (1/2) c sin B * a

  I worked it out. Can you tell me if these are right. <C=56.4 degrees <A=83.6 degrees Area=10095.2 We have to round to the nearest tenths.
