Answer:
16
Step-by-step explanation:
First of all, I think it was "respectively", not "respecfully", =))). A noticeable point.
From the problem, three item's costs are represented by three consecutive even integer.
Thus, we can call cost of spoiler is x, sunroof is x-2, stereo is x + 2. It is conditioned that x is an even number.
Since the sum of the three is 48, we have
(x-2) + x + (x+2) = 48
x+x+x -2 +2 = 48
3x =48
x=16
So the spoiler is 16; thus, the sunroof is 14 and the stereo is 18
8 times 8 is the closest you can get to 71 without going over, since 8 times 9 would be 72.
Let:
the ladder length = l
the distance from the wall and the ladder = x
cos (39) = x / l
x = l * cos (39) = 14 * cos (39) = 10.88 ft
Hope that helps
