[00:00:00]A and B are parallel. C and D are also parallel. Calculate [music] X according to the angles given in the figure. The angle expressions are 20x + 3 and 2x + 30.

[00:00:12]Let's find [music] X.

[00:00:18]Remember, corresponding [music] angles are equal when lines are parallel.

[00:00:26]Here's another pair of corresponding angles.

[00:00:33]Adjacent angles add up [music] to 180°.

[00:00:38]So, we'll add them up, set them equal to 180, and solve for the angle.

[00:00:53]Next, we'll isolate X.

[00:01:05]And that's how we [music] find the solution to this question.
