Question

Solve the triangle.

B = 73°, b = 15, c = 10

C = 39.6°, A = 67.4°, a ≈ 14.5
Cannot be solved
C = 44.8°, A = 62.4°, a ≈ 14.5
C = 39.6°, A = 67.4°, a ≈ 20.3

Answer 1

Don't you an image of the triangle?

Answer 2

since you know the length of opposite side of the given angle, you can apply the law of sines.

Answer 3

Law of sines:
\[\huge\rm \frac{ \sin(A) }{ a }=\frac{\sin(B)}{b}=\frac{\sin(C)}{c}\]
B=given
b=given
c=given
we can use 2nd two fraction to find the angle C
\[\rm \frac{ \sin(B) }{ b }=\frac{\sin(C)}{c}\]
plugin the given values solve for unknown variable.
