An athlete ran 200 meters in 19.19 seconds. suppose that he ran the first half of that race (around a curve) in 10.75 seconds. how long did it take him to run the second half of the race (on a straight track)?

step-by-step explanation:

answer: $1794

step-by-step explanation:

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
