Beginning with problems 1-7, Sal works on the next section of the practice SAT from The Official SAT Study Guide (page 611). The problems include simple algebraic equations, square roots, word problems, and graphing.

The final video of the SAT practice series takes students through increasingly complicated algebra and geometry problems, but Sal works steadily through each mathematical process. At the end of the video he tells students that they are...

So you have a transversal line intersecting two parallel lines and you are looking for a value that would make two corresponding angles congruent. You have all the information needed to write an equation to find the value. So write that...
