Question

A triangle has sides A, B, and C. The angle between sides A and B is `(2pi)/3`. If side C has a length of `36` and the angle between sides B and C is `pi/12`, what is the length of side A?

Answer 1

A=10.75890567 cm

Explanation:

using `a/[sin A]=b/[sin B]`

`36/[sin[[2pi]/3]]=A/[sin[pi/12]]`

`A=sin[pi/12] xx 36/[sin[[2pi]/3]]`

A=10.75890567
