When two straight lines intersect, angles are formed, and the difference between two of them is 54 degrees.

When two straight lines intersect, angles are formed, and the difference between two of them is 54 degrees. (Find all the formed non-rotated corners)

1. One angle equals x degrees.

2. The other angle is (180 – x) degrees.

3. Let’s make an equation and find the degree measure of one angle.

180 – x – x = 54;

180 – 54 = 2x;

x = (180 – 54) / 2 = 63.

Answer: Sharp angles formed at the intersection of two straight lines are equal to x = 63 °.

Blunt 180 – x = 180 – 63 = 117 °.
