The circle is divided into three sectors. The degree measure of the first sector is 80 degrees, which is 60 degrees less than the degree measure of the second sector. Find the degree measure of the third sector.
Let’s calculate the degree measure of the second angle.
80 + 60 = 140 degrees.
Recall that the degree measure of the full angle is 360 degrees.
Knowing that the degree measure of the first angle is 80 degrees, and the second angle is 140 degrees, we calculate the degree measure of the third angle.
360 – 80 – 140 = 140 degrees.
Answer: 140 degrees.
