She needs to earn at least 84 to buy the mp3 player
earnings=earningsperhour times numberofhoursworked
earnings per hour=12 dollars
number of hoursworked=h
therefor
earnings=12 ties h or12h
earnings is at least 84
earnings is greater than or equal to 84
earnings<u>></u>84
12h<u>></u>84

Answer: angle 1 = 110 degrees
This is because angle 1 and the red 110 degree angle are corresponding angles.

Corresponding angles are congruent only when we have parallel lines like this.
