Answer:
Interior = 60°
Exterior = 120°
Step-by-step explanation:
A triangle has 180° in total.
We have 2 angles, 70 and 50
70 + 50 = 120
For Angle U, we do 180-120 = 60
So the interior angle is 60°
A line is straight and is 180°
With angle U being 60°, and being on a straight line, 180-60 = 120
So exterior angle is 120°
