Question

Draw a circle of radius 2.5 centimetres. Draw a triangle of two angles 70° and 50° with its sides touches the circle.

Hint:

To construct a triangle with a given incircle and angles, the key is to find the central angles between the radii to the tangency points. Remember the rule: Central Angle = 180° - Vertex Angle. This is the reverse logic of the circumcircle construction.
