# Thread: Find edge on a scalene triangle knowing 1 angle and 1 edge size

1. ## Find edge on a scalene triangle knowing 1 angle and 1 edge size

Hi all!

Is it possible to find the size of all edges of a scalene triangle knowing that the base edge is 18 mm and the obtuse angle is 135?

My goal is to have a generic formula to calculate the x,y points at the end of a curve knowing the center and the final angle but if someone answers my first question I can do the rest alone.

Thanks!

No. You need to know either one more side or one more angle.
