Solution : #color(red)(b = 7.3681, c = 15.0987, hatC = 120^@#

Given 2a = 10, hat A = 35, hat B = 25#

#hatC = 180 - 35 - 25 = color(red)(120#

Applying Law of Sines,

#color(green)(a/sin A = b / sin B = c / sin C#

#b = (a sin B) / sin A = (10 * sin 25) / sin 35 = color(red)(7.3681#

#c = (a sin C) / sin A = (10 sin 120) / sin 35 = color(red)(15.0987#
