A racing car has a mass of 1,524.6 kg. It starts from rest and travels 19.09 m in 3 seconds. The car undergoes uniform acceleration during the entire 3 seconds. What unbalanced force is applied to?

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.

i believe the answers 600m

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
