Acity planner needs to verify that main street and oak street are parallel. if are supplementary, the streets must be parallel. a) ∠1 and ∠2 b) ∠1 and ∠3 c) ∠2 and ∠3 d) ∠2 and ∠4

Answer;

A) ∠1 and ∠2

Explanation;

Supplementary angles form a straight line and have a sum of 180 degrees. Supplementary angles do not have to be congruent or adjacent. Angle 1 and angle 2 are supplementary angles.

Complementary angles on the other hand are two angles whose sum is 90 degrees. Supplementary and complementary angles do not have to be adjacent (sharing a vertex and side, or next to), but they can be. angles sum right angle.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
