Answer:
56 inches is the horizontal distance from the end of the ramp to the back of the truck.
Step-by-step explanation:
Height of the back of the truck =33 inches
Length of the ramp = 65 inches
Length of the end of ramp to the back of the truck =?
In triangle ABC:
AB = 33 inches
BC = ?
AC = 65 inches
(Pythagoras theorem)
BC = 56 inches

Answer:
See below
Step-by-step explanation:
16 + (18 + 10) = (x + 18) + 10x
16 + 28 = (x + 18) + 10x Add like terms in the parentheses
44 = (x + 10x) + 18 Use the community property to regroup like
terms
44 = 11x + 18 Simply
<u>-18 = -18</u> Substract 18 from both side
26 = 11x Simply
<u>26</u> = <u>11x</u> Divide by 11
11 11
Reduce
So hmm notice the picture below
that's the 30-60-90 rule, notice your triangle, the bottom-left-angle is a right angle, 90°, the angle atop is 30°, so the angle on the bottom-right has to be 60°, thus is a 30-60-90 triangle, and as you can see on the triangle on the left in the picture, those are the ratios for it
so 8 will be x, what is the longer leg or side in yours then? well, is
