Question

Please dont answer with anything bad :((( extremely need help

Answer 1

Answer:

120°

Step-by-step explanation:

The sum of all interior angles is found using (n - 2)180

n is the amount of angles inside the polygon (in this case, 3). Plug in 3 for n:

(3 - 2)180 = (1)(180) = 180

There are 3 sides in a triangle. Divide the total (180) with 3:

180/3 = 60

Next, Subtract 60 from 180:

180 - 60 = 120

120 is your exterior angle.

120° is your answer.

Answer 2

Answer:

120°

Step-by-step explanation:

A line must add up to 180°.

The sum of angles in a triangle also adds up to 180°.

Step 1: Find measures interior angles.

3x = 180

x = 60°

Step 2: Find measures of exterior angels.

x + 60 = 180

x = 120°
