One of the adjacent corners is three times the size of the second. Find these corners.

Adjacent angles are formed when two straight lines intersect. The sum of adjacent angles is 180 °.

1) One of the adjacent angles is x degrees.

2) The second of the adjacent angles is x * 3 = 3x degrees.

3) Let’s compose and solve the equation.

x + 3x = 180;

4x = 180;

x = 180/4 = 45;

x = 45;

Answer: One of the adjacent angles is x = 45 °. The second of the adjacent angles is x * 3 = 45 * 3 = 135 °.
