The sum of all angles (around the black dot) is 360°
All 5 angles (if you forget the red line) are the same; so each angle is 360°/5 = 72°
So Angle 1 is 72°

Step-by-step explanation:
Answer:
1.75 lt (1750 ml)
Step-by-step explanation:
Bottle size conversion
2.5 Lt = 2500 ml
Calculate how much is used to fill glasses
125*6=750 ml
Now you subtract the lemonade used from the bottle size and calc how much is left
2500-750=1750 ml or 1.75 Lt
We just need to make the fractions equivalent, if you take 3/5 and put it in tenths you get 6/10. Which means that the oldest brother has 6/10 the youngest has 1/10 and because we can add those two together and subtract from the total we get the middle brothers amount, 3/10 of the money. Multiply the fractions by the 108 total to get the amount of money that each person has.
6/10*108=64.8
3/10*108=32.4
1/10*108=10.8
To make sure the answers are correct add the values together. 64.8+32.4+10.8=108
The eldest brother has $64.80, the second eldest has $32.40 and the youngest has $10.80.
