A circle is divided into 10 equal parts what is the angle measure of four of those parts

Answer:

Four of those parts will have 144 degrees

Explanation:

                          A full circle will always have 360 degree

If the circle is divided into 10 equal parts,

The angle shall divide in 10 parts:

Each slice angle: = 36 degrees.

1 parts has 36 degrees; so:

Four parts will have: 36 * 4 = 144 degrees.

A circle is divided into 10 equal parts what is the angle measure of four of those parts?

To solve this, We need to divide the number of total parts by 360° (since the measure of a complete angle is 360°) and then multiply it by the number of parts whose measure is to be found.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
