Answer:
<h2>The answer is option A</h2>
Step-by-step explanation:
<h3>
</h3>
<u>First of all cross multiply</u>
That's
g( wd + f ) = a + bc
<u>Multiply the terms at the left side of the equation</u>
We have
gwd + fg = a + bc
<u>Send fg to the right side of the equation</u>
That's
gwd = a + bc - fg
<u>Divide both sides by dg to make W stand alone</u>
<h3>
</h3>
We have the final answer as

Step-by-step explanation:
Answer: the value of | 2x + y | = 1.39
the direction of 2x + y = 21°
Step-by-step explanation:
Given that the vectors x and y are unit vectors that make and angle of 30 degrees with each other.
Let assume that unit vector x is along the positive x-axis, and unit vector y is at +30°.
Therefore
2x-y=
2< 1,0 > - < cos(30),sin(30) >
=<2-(√2)/2, 0-1/2>
and
|2x-y|=√((2-(√2)/2)² + (-1/2)^2)
=1.3862
Therefore the value of | 2x + y | = 1.39
=atan((-1/2)÷(2-(√2)/2))
=atan(1.29289/-0.5)
=-0.369 radians
= -21.143°
Therefore the direction of 2x + y is
21°
