Help me please!!!!!!!!!!!!!!!
irina [24]

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°

Hey there.

8/9d = 28; multiply both sides by 9.

8d = 252; divide both sides by 8.
