The circle is divided into two sectors, the angle of one sector is three times greater than the angle of the second. Calculate the angle of the first.
The whole circle is 360 degrees.
Let’s denote one angle through x. This means that the second angle is 3x. Find how many degrees make up the angle of the sector. We write down the solution.
We write the expression.
3x + x = 360.
4x = 360.
X = 360: 4 = 90.
This means that the angle of one sector is 90 degrees.
90 * 3 = 270.
The angle of the second sector is 270 degrees.
Answer: 270 degrees and 90 degrees.
