The exterior angle equals the sum of two interior opposite angles
x + 90 = 2x + 40
Sum of all interior angles = 180
x + 90 + (x - 10) = 180
Answers:
x + 90 + (x - 10) = 180
x + 90 = 2x + 40
The second car will overtake the first car at about 3 hours and 11 minutes.
50*4.19 hours(it's ahead by one hour)=209.5
66*3.19 hours=210.54
So about that much time.

3/12 or 1/4 is left of the bread
2*4
-----= 8/12 - i did this for a common denominator
3*4
8 1 9
--- + --- = --- i did this to find the total eaten
12 12 12
12 9 3 1
--- _ --- = --- or simplified as ----
12 12 12 4
the total amount of bread left is 3/12 or 1/4 (simplified)
