If 45° and 65° are the angles of a triangle, then find the exterior angle of the third angle (remaining angle).

Interior Angles of a triangle = $$45\degree, 65\degree$$

Exterior angle of a triangle = Sum of interior angles of opposite sides

Solution:  

Exterior angle of the third angle = 45 + 65 

Exterior angle of the third angle = $$110\degree$$​​
