Answer 5

Okay... let's focus on a just a specific part of the dizzying figure for the moment...

Answer 8

the choices

Answer 9

You understand so far?

Answer 10

yea

Answer 11

(2x-30) + y = 180°
x + y + 45 = 180°
for a straight line sum of the angles =180 °

Answer 12

ok

Answer 13

The angle I marked, the one equal to 2x + 30
It will be congruent to THIS angle... why?

Answer 14

2x - 30.
Sorry, my bad.

Answer 15

alternate exterior angles theorem

Answer 16

That is correct.
Now, it just so happens that this angle is divided into two, which measure...
Means the angle I marked second is actually equal to their sum.

We can now conclude that 2x - 30 = ...?
