A right triangle has the two legs that form an angle of 90°, which means that the two legs are perpendicular.
In order to prove that FGH is a right triangle, you need to calculate the slopes of the lines passing through its vertexes and see if there is a pair of opposite reciprocals:
m = (y₂ - y₁) / (x₂ - x₁)
m(FG) = (-9 - 4) / (5 - 2) = -13/3
m(FH) = (-4 - 4) / (-3 - 2) = 8/5
m(HG) = (-4 -(-9)) / (-3 - 5) = -5/8
Since m(FH) and <span>m(HG) are opposite reciprocals, FH is perpendicuar to HG and FGH is a right triangle.</span>

Step-by-step explanation:
On each median the distance from the vertex to the centroid is twice the distance from the centroid to the midpoint, or
the distance from the centroid to the midpoint is one third of the median

LF = 2 × HL = 2 × 30 = 60
HF = HL + LF = 30 + 60 = 90

Let that "number" be x. You have the equation:
(2 / x) - 6
I hope this helps. Is this what you're asking for?
