Answer:
C)
Step-by-step explanation:
Slope of KL = 2/2 = 1.
Slope of MN = 2/2 = 1.
Slope of LM = -1/2.
Slope of NK = -1/2.
The slopes of opposite sides KL and MN are equal.
The slopes of opposite sides LM and NK are equal.
Since quadrilateral KLMN has two pairs of opposite sides that are parallel, it is a parallelogram.
The magnitude and the direction of the <em>resulting</em> vector is 3 and 0°, respectively.
<h3>Procedure - Determination of a vector by subtraction</h3>
Let assume that angles are in standard position. According to the statement, we have following model for the direction of the <em>resulting</em> vector in terms of the vectors known in statement:
(1)
Where is the resulting vector.
If we know that , and , then we have the following expression:
Then we have the following system of linear equations:
(2)
(3)
By (3):
By (2):
Hence, the magnitude and the direction of the <em>resulting</em> vector is 3 and 0°, respectively.

Remember
√xy=√x times √y
and
x^-m=1/(x^m)
simplify parenthasees firs
(√9x^4y)=√9 times √x^4 times √y=3*x^2*√y=3x^2√y
now we have
(3x^2√y)^-3=1/((3x^2√y)^3)=1/(27x^6y√y)
Answer:
x=50 because of the propertie of angle
