In the following diagram, A II B.

Use complete sentences to explain how the special angles created by the intersection of A and B by D can be used to solve for x.
Solve for x, showing all of your work.
Find the measure of ∠6.

Answer 1

The special angles created can be used because they are supplementary and add up to 180 against the line D. you can solve for x by setting the equations equal to 180

4x+5+3x+7=180

7x+12=180

7x=168

x=24
