Answer:

8

Step-by-step explanation:

The perimeter is adding all 4 sides

We know one side is 9

The other three sides are in the ratio

1:2:4

Multiply by x to give the side lengths

x, 2x, 4x

The Perimeter is

9+ x+2x+4x=65

9+7x=65

Subtract 9 from each side

9-9 +7x =65-9

7x = 56

7x/7 = 56/7

x=8

The shortest side is 8

we just need add x next to ratio and sum them all to get perimeter

9 + x + 2x + 4x = 65

7x = 56

x = 8

well since 8(x)<9<16(2x)<(32(4x), then

the shortest side is 8

Triangles QVS and RTS are similar. Find side VS.
tekilochka [14]

In order to solve the equation, set up a proportion. Use the similar sides together!

1. 16/8 = x/20.... Similar sides are in one ratio and they equal another ratio...."x" represents the side of VS

2.Solve for "x" by cross multiplying: 8x = 320

3. Divide by 8 to find "x": x = 40

Side VS equals 40. Hope this helped :)
