Answer:
m = 5
Step-by-step explanation:
We are told that the two triangles are similar. Thus, each side of the larger triangle is the same multiple of the corresponding side in the smaller triangle.
Thus, 12 = k(7.2), where k is the constant of proportionality.
Solving this for k, we get
k = 12/7.2 = 1 2/3
Thus, side m is 1 2/3 times 3, or 5/3 times 3, or just 5.
m = 5
Pythagorean theorem(√82)^2 = 9^2 + x^2
x = 1 cm
15^2 = 9^2 + y^2
y = 12 cm.
12-1 = 11
Area = 9*11 = 99 cm^2
Answer:
A. The distance of a race.
Step-by-step explanation:
If a person wants to know the amount of time it would take to finish the race would involve the function of how long the race would have to be because the entry fee of the race and the people involved in the race don't have anything to do with the amount of time it takes to finish the race.
