Question

A triangle has sides A, B, and C. The angle between sides A and B is `(7pi)/12`. 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=6.6987298106

Explanation:

`(25)/(sin((7pi)/(12)))=a/(sin(pi/12))`

`(25)/(sin((7pi)/(12)))xx sin(pi/12)=a`

a=6.6987298106
