Hello!
As you can see,this triangle has a 97° angle, which means it is obtuse. As you can see, all of the lines are different lengths, so it is scalene.
Therefore, our answer is B) obtuse, scalene.

Speed = distance/time
distance = speed * time
let x = time covered by running
15 = run distance + walk distance
15 = 9(x) + 3(3-x)
15 = 9x + 9 - 3x
15 - 9 = 6x
6 = 6x
x = 1 hour
Therefore:
Running distance = speed * time
RD = 9km/hr * 1 hr
RD = 9km
To get the answer to this problem, we have to divide $5400 by 360.
5400/360 = 15
The correct answer to this question is $15 dollars per square footage.
