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°
