Calculate the Beta (β) Angle: Perpendicular Lines in Coordinate Plane

Question

Calculates the size of the angle $\beta$

00:03 Let's calculate angle B together.

00:08 We know that these lines are parallel based on the given data.

00:13 Remember, corresponding angles between parallel lines are equal.

00:23 This angle is supplementary to a straight angle.

00:28 Let's focus on isolating angle B now.

00:38 And that's how we find the solution to the question!
