Find the measure of each
exterior angle of regular polygonof a 9sides.

40

Step-by-step explanation:

Any regular polygon has exterior angles  = to 360 / number of sides.

so a 9-gon has 9 sides. The exterior angle = 360 / 9 = 40

Each exterior angle will be 40 degrees.

Try it with simpler n-gons. A triangle has 3 sides. The exterior angle is 360 / 3 = 120

A square has 4 sides. Each exterior angle is 360 / 4 = 90

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
