Answers:
In order:
x=35º, 50º, 91º, 118º, 42º, 104º, 112º, 130º, 40º
Step-by-step explanation:
For numbers 1,3,4,5, & 7, since the angles are same side interior, together they will add up to 180º. To find x, you subtract the given angle from 180º.
Example, #1: x=180-145, x=35º
For 2,6,8,9, since the angles are alternate interior, they will be congruent.
Example, #8: The given angle is 130º, so x will also be 130º.
I reccomend searching up alternate interior/exterior, same side interior/exterior, and corresponding angles on the internet.
Hope these are correct!
