As a property of the triangle states that -

Any exterior angle of a triangle has a measure, which is the sum of its two opposite interior angles .

Therefore, let the exterior angle we are required to find out, be x,                                

So, x = 60° + 80° = 140°

So, answer: The exterior angle is of measure 140°
