Answer:
∠4 = 152°
Explanation:
The image you've uploaded presents a pair of parallel lines cut by a transversal line, creating multiple angles. To find the measure of angle 4, we need to consider the properties of angles formed when two parallel lines are intersected by a transversal.
I have attached the relevant properties as an image attachment for you to view. Using this information, we find that the given 28° angle is supplementary with ∠4. This means that they add up to 180°.
So,
⇒ ∠4 = 180° - 28°
∴ ∠4 = 152°
