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°
1/4n I think I hope this is correct
1. DE || AB - Given
2. DE 1/2 AB - side splitter theorem
3. CD/CA = CE/CB - sst = proportioned sides
The answer is 2, because if a number is a whole number, for example 2, you must multiply it by a number with 2 decimals, in this case 17.77, to get 34.44 based on this example.
*There are some cases where this doesn't apply, I think, but it does apply for your question.
