Answer:the measure of angle 4 is 48 degrees
Explanation:
The blue horizontal line crosses the red line at a point. Therefore, angle 2 and angle 4 are vertically opposite angles. Vertically opposite angles are equal. Therefore,
If the measure of angle 2 is 48 degrees, then the measure of angle 4 is also 48 degrees.
We can check by looking at the fact that the sum of the angles on a straight line is 180 degrees. It means that
Angle 1 + angle 2 = 180
Angle 1 = 180 - 48 = 132
Also,
Angle 1 + angle 4 = 180
Angle 4 = 180 - 132 = 48
