Asked by Taliyah

Given ABC with a = 9, b = 5, and mA 80° , find mB . Round the sine value to the nearest thousandth and answer to the nearest whole degree.
I got 33° am I right?
Answered by Steve
sinB/b = sinA/A
sinB/5 = sin80°/9
sinB = 0.5471
B = 33.17°

good work

Use Law of Sines:
SinA/a = SinB/b.
Sin80/9 = SinB/5,
SlnB = 5/9 * Sin80 = 0.5471.
B = 33.o.
