Answer: You are correct. The answer is choice C.
The sum of the vectors is the resultant vector, which is where the net force is directed.
An example would be if you had a ball rolling on a table and you bumped the ball perpendicular to its initial velocity, then the ball would move at a diagonal angle rather than move straight in the direction where you bumped it.
Acceleration is the change in velocity over time, so the acceleration vector tells us how the velocity's direction is changing.
Answer:
ABCD is a parallelogram/Given
Line AB is parallel to line DC/Opposite sides of a parallelogram are equal
Line FD is congruent to Line FD/Reflexive property
Line BE is congruent to line BE/Reflexive property
Line AC is congruent to Line AC/Reflexive Property
Angle A is congruent to Angle BCD by Alternate Interior Angle Theorem
Angle BCD is congruent to Angle FCE by Vertical Angles Theorem
Angle A is congruent to Angle BCD by Transitive Property
Remark
The easiest one to start with is the solution to y. The angle that is supplementary to 6y is a 90o angle. You could do this 2 ways.
Supplementary angles add up to 180o.
So 6y + 90 = 180 Subtract 90 from both sides.
6y + 90 - 90 = 180 - 90
6y = 90 Divide by 6
6y = 90 / 6
y = 15
Solve for x
Interior angles created by a transversal cutting 2 parallel lines also add to 180o
That means that 100 + x = 180 Subtract 100 from both sides.
100 + x - 100 = 180 - 100
x = 80 degrees.
