Thread: Sides of triangle: a= p^2+p+1, b=p^2+2p, c=2p+1

Sides of triangle are a= p^2+p+1, b=p^2+2p, c=2p+1. Calculate medium size angle.

If p is not equal to 1, side A ( ). Simply substitute a number such as 10 for p.
Also, please use the [tex] tag for formulas.

It can be equal to 1.
It's not so simple i used law of cosines to find angle α which is pi/3 but i don't know how to calculate β and γ.
