34 with 6

56 with 8

90 with 10

ooooh just like we divide these two to get the scale factor

A hypotenuse is the side of a right triangle ( one having a 90° angle in it ) that is opposite to the 90° angle.

]]>8) I get 10 is the hypotenuse so it is across from the side with a length of 10. You can get the next two sides and angles.

]]>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
