The circle was divided into 3 sectors. the angle of the first sector is 131 °. the second is 9 ° less

The circle was divided into 3 sectors. the angle of the first sector is 131 °. the second is 9 ° less. find the third corner of the sector.

Let us determine with the help of how many degrees it will be possible to represent the angle of the second sector of the circle, when from the condition of the task we know that it is 9 ° less than the angle of the first sector:

131 – 9 = 122.

As we know from the current school curriculum, the degree measure of the circle is 360 °.

Let’s determine with the help of how many degrees it will be possible to represent the angle of the third sector of our circle:

360 – (131 + 122) = 360 – 253 = 107.

Answer: With such initial data, the angle of the third sector is 107 °.
