Use the law of sines to solve ABC when a=1.43,b=4.21, and A=30.4 degrees. If no solution exists,write none

Step 1. The Law of Sines for this example is given as sin%28B%29%2Fb=sin%28A%29%2Fa=sin%28C%29%2Fc

Step 2. Then

sin%28B%29%2Fb=sin%28A%29%2Fa

sin%28B%29=b%2Fa%2Asin%28A%29

sin%28B%29=4.21%2F1.43%2Asin%2830.4%29=1.48979.

Step 2. Since sin(B) must be less than 1, there is no solution to this problem.

Step 3. ANSWER: None.

I hope the above steps were helpful.
