(show work if you can) The two figures are scaled copies of each other. a. What is the scale factor that takes Figure 1 to Figure 2?
b. What is the scale factor that takes Figure 2 to Figure 1?

a) Scale Factor = 3

b) Scale Factor = 1/3

Step-by-step explanation:

In the first figure, the length between points A and C is 2.

In the second figure, the length between the corresponding points for A and C is 6.

6 · = 3

So, your scale factor would be 3.

The opposite for question b.

50.6

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
