# An angle of 160 degrees is divided by the ray at the apex of the angle into two angles, one of which is 20 degrees less

| We draw up an equation in which one of the two obtained angles is written as x °.

Since we know from the problem statement that the second angle is 20 ° less than the first, then its value will be: x – 20 °.

Since the sum of the two angles is 160 °, we get the following equation:

x + x – 20 = 160.

2 * x = 160 + 20.

2 * x = 180.

x = 180/2 = 90 ° (first angle).

x – 20 = 90 – 20 = 70 ° (second angle).

Answer:

90 ° and 70 °.
