Question

Did I do it right??? Please respond.

Answer 1

Fraid not.  This time, you did it left.

The tool to use is "Vertical" angles are equal. (They don't add up to 180 degrees.)

3y + 120 = 5y + 100

(you should fill in the missing steps)

y = 10°

The upper/lower pair of vertical angles are both 150°.

.

2x = 6x - 60

(you should fill in the missing steps)

x = 15°

The left/right pair of vertical angles are both 30°.

It's any two angles NEXT TO each other that add up to 180°.

Notice here that (150° + 30°) = 180° .
