Question 850741: Use the Law of Sines or Law of Cosines to solve the triangle. Round answers to the nearest tenth.
The triangle gives the measure of Angle B and sides a and c. The measurements are:
Angle B = 28 degrees
Side a = 18
Side c = 15

You can put this solution on YOUR website!
Angle B = 28 degrees
Side a = 18
Side c = 15
----------------
Since you have 2 sides and the included angle, use the Cosine Law
b%5E2+=+a%5E2+%2B+c%5E2+-+2ac%2Acos%28B%29
