Answer 1

Answer:

Make me brainliest

Step-by-step explanation:

Every polygon has total 360 degrees in exterior when added. So,4 x 360=1440 degrees.

Answer 2

Answer:

72°

Step-by-step explanation:

So lets make outer angle as x

The inner angle is 4 times the outer so it is 4x

So,

4x + x = 360°

5x = 360°

x = 360° ÷ 5

So x = 72°

So outer andle is 72°
