Which of the following statements are true? Select all that apply. If the scale factor is 1, the image is congruent to the pre-image.
The coordinates of the image vary inversely with the coordinates of the pre-image.
The coordinates of the image vary directly with the coordinates of the pre-image.
If the scale factor is greater than 1, the coordinates of the image are less than the
coordinates of the pre-image.

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.

well kind of. you get friend requests. and you can accept them or not so yes.
