Plz HELP! WILL GIVE BRAINLIEST!<br><br>1. Consider the picture below. Find the measure of ∠CEA.
pashok25 [27]

Answer:

  103°

Step-by-step explanation:

The marked angles have the same measure, so ...

  14x+7 = 12x +17

  2x = 10 . . . . . subtract 12x+7

  x = 5 . . . . . . . divide by 2

  (14x +7)° = 77°

∠CEA is supplementary to the marked angles:

  ∠CEA = 180° -77°

  ∠CEA = 103°
