Question

B=12.1 degrees b= 15 a= 23.9

Answer 1

This is the ambigious case, there are 2 cases possible

sinA/23.9 = sin 12.1/15
sinA = .33399
angle A = 19.5° or 160.5°

case1:
A = 19.5, B=12.1, then C=148.4
c/sin148.4 = 15/sin12.1
c = 37.5

case2:
A= 160.5, B=12.1, then C = 7.4°
c/sin7.4 = 15/sin12.1
c = 9.23
