Using ruler and a pair of compasses only construt triangle ABC such that AB 8cm angle ABC 60° and angle BAC 75°

Question

Locate the point o inside ∆ ABC equidistant from A B and C
Construct the circle with center o which passes through A

Answer 1

If you can construct a 60° angle, you can construct a 75° angle
(bisect 60° twice to get 15° and add that to 60°)
The point O is the circumcenter, and lies where the angle bisectors meet.
