What is the definition of similarity

Similarity is the state or fact of being similar

similarity means something showing some resemblance but aren’t the same an example can be twins show a lot of resemblance but aren’t quite the same as there other

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

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.
