Question

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles.

B = 40°, b = 25, c = 26

Choices:
A = 98°, C = 42°, a = 16.2; A = 2°, C = 138°, a = 16.2
A = 98°, C = 42°, a = 38.5; A = 2°, C = 138°, a = 1.4
A = 92°, C = 48°, a = 38.9; A = 88°, C = 132°, a = 38.9
A = 92°, C = 48°, a = 16.1; A = 88°, C = 132°, a = 16.1

Answer 1

A = 98°, C = 42°, a = 38.5; A = 2°, C = 138°, a = 1.4

Explanation:

Use the law of sine

a/sinA=b/sinB=c/sinC
