Answer:
90°
Step-by-step explanation:
Two lines intersect each other at a right angle, making them perpendicular. Thus, the resulting angles will all be 90°, making ∠4 = 90°.
Alternatively, we can use the supplementary angles equation.
Let's call the right angle marked in the picture ∠5.
∠4 + ∠5 = 180°, since the line is also a straight angle which measures 180°.
∠4 + 90° = 180°
∠4 = 90°
Either way, ∠4 = 90°
Hope this helps!
