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.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
