A polygon will be dilated on a coordinate grid to create a smaller polygon. The polygon is dilated using the origin as the center of dilation.
Which rule could represent this dilation?
(x, y) +(0.5-x, 0.5-y)

(x, y)+(x-7, y-7)
(x, y) + x, x, y)
(x, y) +(0.9 x, 0.9 y)

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.

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
