Answer:
The measure of the angles in degree is 57.5 degrees
Step-by-step explanation:
If two angles are congruent, they are equal in value
Let the number be x
2x + 3 = 3x-54.5
Thus;
3x-2x = 54.5 + 3
x = 57.5
Jean's car :
(12 1/2) / (5/12) =

25/2 * 12/5 =
150/5 =
30 miles per gallon
Miranda's car :
(20 5/7) / (5/7) =
(145/7) / (5/7) =
