Find the measure of one interior angle of a regular 20-gon.

162°

Step-by-step explanation:

Using exterior angle methods,

sum total of exterior angle of polygon =  ³⁶⁰/ₙ , where n is the size of the polygon.                                                 =   ³⁶⁰/₂₀

One exterior angle                               =  18°.

Now the interior angle                          = 180° - 18° ( angle on a straight line )

Therefore, the measure of the interior angle = 162°.

Not , Other methods can still be applied.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
