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

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)
