The measure of an exterior angle of a regular polygon is given below. Find the measure of an interior angle. Then find the number of sides. 45

Answers are below

Step-by-step explanation:

To find the measure of an interior angle, subtract 45 from 180.

180 - 45 = 135 degrees for an interior angle

To find the number of sides take 360 divided by 45

360/45 = 8 sides on the shape.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
