Question

Use the law of sines to solve the triangle, if possible. b = 49.31 yd, c = 49.31 yd, C = 73.08 degree B = (Do not round until the final answer. Then round to two decimal places as needed.) There is no solution. Find the measure of angle A. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A = (Do not round until the final answer. Then round to two decimal places as needed.) There is no solution. Find the length of side a. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. a = yd (Round to two decimal places as needed.) There is no solution.

Explanation / Answer

by law of sines a/sinA=b/sinB= c/sinC

b/sinB= c/sinC

49.31/sinB= 49.31/sin73.08o

=>B=73.08o

A+B+C=180o

A+73.08o+73.08o=180o

A=33.84o

a/sinA=b/sinB

a/sin33.84o=49.31/sin73.08o

a=49.31sin33.84o/sin73.08o

a=28.70 yd
