Question

Given  with a = 10, b = 16, and m(angle)A=30°  , determine both possible values for m(angle)B .

oobleck · Accepted Answer

sinB/b = sin30°/a sinB/16 = 0.5/10 sinB = 16*0.05 = 0.8 You know there are two angles B with sinB = 0.8 one in QI and the other in QII

I didnt understood how, I did the procedure as you said and my only results are 53°, 127° 53°, 133° 64°, 127° no solution I can choose between those

oobleck · Answer

so, what angle B has sinB = 0.8 ? I promise you, it's in the list.

Risotto Nero · Answer

Angle ∠ B = β = 115.736° = 115°44'11″ = 2.02 rad right? so in these case there is no solution right?
