An object of mass =4 kilograms falls vertically to the ground under the action of the earth gravitational acceleration of magnitude =10 meters per second squared. Denote by vertical coordinate, positive upwards, and let =0 be at the earth's surface. Recall that the force on the object in this situation is =−, where the negative sign says the force points downwards

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.
