The correct answer for this question is this one: 5 / 7
<span>There exists the same question from other source that has the continuation of the problem. <em>Use proportions to test your measurements and see if they match this ratio. Height is 5ft</em>
So this how to solve this:
Set the equation as:
7x = 5
x = 5 / 7</span>
C because you have to multiply the four measures together.
<span>5 = 15
---------
8 = x
cross multiply
5x =120
5x÷5 = 120÷5
x = 24
Check
5/8 = 15/24
.625 = .625

1)
8² + 15² = 17²
64 + 225 = 289
This is true, so the triangle is a right triangle.
2)
4² + 12² = 13²
16 + 144 = 169
This is false, so the triangle is not a right triangle.
3)
20² + 21² = 27²
400 + 441 = 729
This is false, so the triangle is not a right triangle.
4)
28² + 45² = 53²
784 + 2,025 = 2,809
This is true, so the triangle is a right triangle.
