The sum of two angles formed by two intersecting straight lines is 148 degrees.

If the sum of two angles formed by two intersecting straight lines is 148 degrees, then the sum of two opposite angles, since the sum of two adjacent angles is 180 degrees. This means that each angle is 148/2 = 74 degrees, since the opposite angles are equal to each other.
Knowing that the sum of two adjacent angles is 180 degrees, we find the remaining angles 180 – 74 = 106 degrees.
This means that when two straight lines intersect each other, angles of 74, 74, 106 and 106 degrees are formed.
