Question 181598
Please help me!! I am trying to help my son with his trigonometry homework and I am clueless. We have an oblique triange with angle B measuring 46.3 degrees, angle C measuring 21.2 degrees and angle A measuring 112.5 degrees. Side a = 9.2. What is the measurement of side b?
-------------------
Use the Law of Sines:
b/sin(B) = a/sin(A)

b/sin(46.3) = 9.2/sin(112.5)

b = sin(46.3)[9.2/sin(112.5)]

b = 7.199
