<h3>
Answer: Choice D) </h3>
Work Shown:

We must require that
and
to avoid having 0 in the denominator. This is why choice D is the answer.
There are two answers:
B) 5
C) 8
==============================================
Explanation:
If we had a triangle with sides a, b and c, then we can say
b-a < c < b+a
where b is larger than 'a'. This is the triangle inequality theorem
In this case, a = 5 and b = 9 so,
b-a < c < b+a
9-5 < c < 9+5
4 < c < 14
Telling us that c is some number between 4 and 14, not including either endpoint. If c is a whole number, then c could be any value from this set: {5,6,7,8,9,10,11,12,13}
We see that the numbers 5 and 8 are in this set. The values 3 and 15 are not in the set.
30 quarters because you times 6 by 5 and that equals 30 than you divine that by 4 and that 7.5
Answer:
The length of the ramp is 13 ft according to the Pythagorean theorem but I don't have an idea about the angle incline.. we must trigonometry to find it .
