Question

A triangle has sides A, B, and C. The angle between sides A and B is `pi/3`. If side C has a length of `25` and the angle between sides B and C is `pi/12`, what is the length of side A?

Answer 1

side `a=7.47146`

Explanation:

Use Sine Law

`a/sin A=c/sin C`

`a=c*sin A/sin C=(25*sin (pi/12))/sin (pi/3)=7.47146`
