Step-by-step explanation:
let the angle be x
20+4x+x=180
20+5x=180
5x=160
x=32
4500 meters. You find this by adding 1/3 and 2/5 which equals 11/15. This means that the remaining 4/15 is 1200 meters long. Divide 1200 by 4 in order to find the distance per 1/15 and you get 300. Multiply 300 with 15 to get the total distance of the race.
Answer:
Why is this long?
