Margot is looking at some information for the obstacle course she is interested in completing the x-coordinate is the number of the obstacle, while the y-coordinate
is the average time to complete the obstacle, measured in minutes
(1.6 25), (2.6875), (3, 7.5625), (4,8,31875)
margot use an explicit formula to find the average time she will need for the 8th obstacle.
(8) 11(6.25): (8) 409782
(8) = 6.25(1.1) (8) = 12.179
(8) = 11(625) (8) = 2561137
(8) = 6.25(1.1) (8) 13.397

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

25.45584

the correct answers i think are b. and d.

give me brainliest if it is correct!

step-by-step explanation:

find the area of the triangle then multiply by 2 then add the area of the parollelegram multiplied by 2
