Hi I was wondering if my answers for the following are correct and I need help answering
number 8 please.

7. Polygon A has sides of 4, 3, 5, and 3. Polygon B has sides of 8, 6, 10, and 6. What are the two possible scale factors here? Explain.

7. In lesson #8 the first example says to divide the bigger polygon's sides by the smaller polygon's sides, but in example 3 it just divides the first angle from A with first angle from B but B angles are bigger than A angles. I am going to do the same thing example 3 did and here is my answer:

To get the scale factor first I have to divide the sides by each other like this:

4/8 = 1/2
3/6 = 1/2
5/10 = 1/2
3/6 =   1/2
So, the scale factor is 1:2

8. A triangle has angles of 34 degrees, 56 degrees, and 90 degrees. It also have sides of 6, 8, and 10. Which side is across from which angle?

9. A triangle has one angle measuring 52 degrees, and one angle measuring 18 degrees. What is the measure of the third angle?
9. Triangles must add up to 180 degrees. 52+18=70
180-70= 110 therfore the measure of the third angle is 110

10. A right triangle has a 90 degree angle, and an angle x. What will the measure of the third angle be?
10. Trangles must add up to 180 degrees. So the equation would be 90+x+A=180
A is representing the measure of the third angle.

90+x+A=180
Subtract 90 from both sides of the equation.
A+x=90
Subtract 'x' from each side of the equation.
A=90-x

Thanks
