Determine the least possible value for b to the nearest tenth if a = 20°, a = 7, and b = 11.

Using sine law we get -- 

=> sin A / 7 = sin B / 11 

=> Sin B = (11/7) . sin A 

=> sin B = ( 11 x sin A ) divided by 7 = 11 sin 20 / 7 

=> sin B = 0.537460225 

=> Angle ( B ) = sin⁻¹ (0.537460225) = 32.5 degree
