The sum of the three angles formed by the intersection of two straight lines is 254 degrees.

The sum of the three angles formed by the intersection of two straight lines is 254 degrees. Find the length of each angle.

To solve this problem, remember that when two straight lines intersect, two pairs of vertical angles are formed. The vertical angles are equal. Knowing. that the sum of the three angles is 254 degrees, we calculate the degree measure of the fourth angle.
360 – 254 = 106 degrees.
Thus, the degree measure of two intersecting angles is 106 degrees. Let’s calculate the degree measure of two other angles equal to each other.
(360 – 106 * 2) / 2 = (360 – 212) / 2 = 148/2 = 74 degrees.
Answer: 106 °; 106 °; 74 °; 74 °.
