In this problem, there are 2 similar triangles: triangle FMN and triangle FGH.
Their ratio to each other is 1:2 which we know by the midpoints.
If they have a ratio of 1:2, line segment GH is the 2 times of line segment MN.
To find x:
An estimate for the percent equivalent of 7/15 is 46% i think

<span>Once upon a time there was a surprise for a boy named Justin ,his 4 friends ordered a pie because it was a surprise soccer party. Only 1 out of the 4 boys got to eat the pie since they all wanted to play soccer. Hope this helped :)</span>
Making the usual substitutions (x=r·cos(θ), y=r·sin(θ)), you have
(r·cos(θ))² +4r·cos(θ) +4 + (r·sin(θ))² -4r·sin(θ) +4 = 8
r(r +4·cos(θ) -4·sin(θ)) = 0
Dividing by r then subtracting the non-r terms gives
r = 4(sin(θ) -cos(θ))
