Since angle B is not 90, side b must be one of the legs of the triangle. But side a could be either the other leg or the hypotenuse. So this problem will have two solutions:
  • If side a is the hypotenuse then use the equation:
    sin%2851%29+=+b%2F3.4
  • If side a is the other leg then use the equation:
    tan%2851%29+=+b%2F3.4
