Question

Determine a value for b such that a triangle with A = 42o and a = 7 has two solutions.

Answer 1

B=10 
sides (a,b,c): 7, 10, 9.4873 
angles (A,B,C): 42°, 72.921°, 65.079° is an acute scalene triangle 
(x,y) Vertices: A (4.2137,9.0689) , B (7,0) , C (0,0)
Second solution: 
sides (a,b,c): 7, 10, 5.3756 
angles (A,B,C): 42°, 107.079°, 30.921° is an obtuse scalene triangle 
(x,y) Vertices: A (8.5788,5.1386) , B (7,0) , C (0,0)
