The circle is divided into three sectors. The angle of one sector contains 80 degrees, and the angles of the other two sectors are equal to each other. How many degrees do these angles contain?

Since we are dealing with unknown numerical values, we will designate the second angle as xo. Accordingly, the third angle will also be equal to xo.
All of these sectors together make up a circle, which means that the sum of all their angles is 360 degrees.
Let’s make an equation.
80 + x + x = 360.

2x = 280.

x = 280/2.

x = 140.

Since we marked the second and third angles as x, they are equal to 140 °.

Answer: 140.
