Example 1: Given with, b = 15cm, and, solve the triangle. Solution 1: If = 48.20, then = 97.80. This means that A is the largest angle of the triangle and side ‘a’ is the longest side. However, if = 131.80, then A = 14.20. In this case A is the smallest angle of the triangle and then side ‘a’ is the shortest side.
