1. The problem statement, all variables and given/known data A triangle had area of 21 cm² and two of its sides are 9 cm and 14cm long. Find the possible measures of the angle formed by these sides? 2. Relevant equations Area= 1/2abSin(C) 3. The attempt at a solution 1/2 (9)(14)Sin C = 21 --> Sin C = (1/3) approx 19.5 or 160.5 I'm just not sure if i did it right does this seem correct?
