Answer:
1) F=25, G=65, and H=90 because similar triangles share similar angles but different sides, meaning the angles of triangle KJL are equivalent to the angles of triangle FGH.
2) Sides HG/LJ and FG/KJ equal to 2/1 as well because every side is multiplied by the same number to either enlarge or lessen the shape. Because of this, all ratios of original measures to altered ones will stay the same (2/1).
3) The correlating side of UV is RS and taking into consideration that the scale factor is 5/2, all we have to do is multiply 5/2 by 3.5ft , which gives us 8.75ft.
