The circle is divided into 3 sectors. the degree measure of the first sector is 80 degrees, which is 60 degrees less than the second sector. find the degree 3 sectors.

Let’s calculate the degree measure of the second sector, if it is 60 ° more than the first sector:

80 + 60 = 140 °.

Let’s calculate the sum of the degree measures of the first and second sectors:

80 + 140 = 220 °.

Let’s calculate the degree measure of the third sector, if the sum of all sectors of the circle is 360 °:

360 – 220 = 140 °.

Answer: the degree measure of the third sector is 140 °.
