Finding Angle α: Using 83° and 29° in Parallel Lines

Question

a,b,c parallel to one another

Find a $\alpha$

00:05 Let's find the angle together.

00:11 Remember, corresponding angles are equal when lines are parallel.

00:21 We have a pair of corresponding angles here.

00:27 Adjacent angles add up to 180 degrees.

00:32 So, let's add them up, set it equal to 180, and find the angle.

00:41 Now, we isolate the angle to solve it.

00:50 And that's how we solve this problem!
