The scale factor is 0.25, not 4 in this case. You can determine this by looking at the comparison of the triangles. The first triangle is 4.4 and the second one is 1.1, so the scale factor is determined by looking at what is happening to the first one to result in the second.

0.25 is 1/4. The second hypotenuse is 1/4 the hypotenuse of the first one.

Answer: 0.25 is true, so 4 is false.

Scale factor = new size/ original size

scale factor = 1.1 ÷ 4.4

scale factor = 0.25

I'm stuck on this homework question. I forgot the formula to find the side. This is 9th grade geometry.

Answer:

x = 2root(22)

see image.

Step-by-step explanation:

The triangle shown is one big triangle cut into two more smaller triangles: one medium-sized and one smaller.

ALL THREE TRIANGLES ARE SIMILAR BY AA.

Set the two smaller triangles up so you can see the corresponding sides. x is the short leg in one triangle and it is the long leg in the smallest triangle. Set up a proportion.

22/x = x/4

crossmultiply

x^2 = 22•4

x^2 = 88

square root both sides.

x = sqroot(88)

x = 2sqroot(22)

see image.
