since all interior angles in a triangle must be 180°, that means that C = 180 - 75 - 34.6 = 70.4. Let's find AD, which is the other sides pair length.
now, check the picture below, let's find the altitude of the parallelogram.

Answer:
- first car: 25 mpg
- second car: 15 mpg
Step-by-step explanation:
Let x represent the fuel efficiency of the car that used the most gas. Since the sum of the fuel efficiencies is 40 mpg, the other car had a fuel efficiency of (40-x). Then the combined miles driven is ...
40x +25(40-x) = 1225
15x = 225
x = 15
(40-x) = 25
The first car got 25 miles per gallon; the second car got 15 miles per gallon.
_____
We made use of the relation ...
gallons × (miles/gallon) = miles
300,000,000+010,000,000+9,000,000+700,000+60,000+3,000+100+60+3
