Answer 5

So it it clear that these two vertical angles are vertical, so they are congruent!

Answer 6

right

Answer 7

As the are congruent, their measures are the same.

So you need to equate their measure and create an equation!

Solve this equation for x, you could find out the value of x, then calculate the measure of the angle you want.

Answer 8

how..

Answer 9

These are two congruent angles, so the measure of the left is equal to the measure of the right.

\[4x+6=7x-21\]
\[21+6=7x-4x\]
\[27=3x\]
\[x=9\]
