In a 30 60 90 triangle, the short side = one half the hypotenuse = 4.5
The middle side = short side * sq root of 3
So, the middle side = 4.5 * sq root of 3 (

Perimeter = 4.5 + 7.7942 + 9
Perimeter =

Ratio = 2:3 = 2/5
Distance between the x coordinates: 3
Distance between the y coordinates: 7
x: 3 * 2/5 = 1.2
y: 7 * 2/5 = 2.8
x coordinate of point: 6 - 1.2 = 4.8
y coordinate of point: 1 + 2.8 = 3.8
So the point that divides the segment AB in the ratio of 2:3 is (4.8 , 3.8) or (24/5 , 19/5)
Hope this helps :)

Simplify x ------- first, the answer should be x -------
3 4 1.5
After that multiply that to x------
3
Like so. . . .
1 4 8
x------- * x------- my answer added up to 0.88 or 1 if you were to round up 0._
1.5 3
Since its 5 or higher you round up so I got 1 whole.
If it's doesn't add up to you I'm sorry.
