Question

Which is the approximate measure of angle Y? Use the law of sines to find the answer.

Answer 1

Sin (Y)/ 2.7 = sin(63)/2.8
Y=arcsin((2.7 sin 63)/2.8
Y= 59.23 degrees

Answer 2

siny/2.7=sin63/2.8

siny=2.7sin63/2.8

y=arcsin((2.7sin63)/2.8)

y≈59.23° (to nearest one-hundredth of a degree)
