Find the vector reciprocal to set. a= i+2j+2k, b= 2i+3j+k, c= i-j-2k

inn [45]

Answer:

I just do a' as a sample. You calculate b' and c'

Step-by-step explanation:

$a'=\frac{b\times c}{a\bullet (b\times c)}, b' = \frac{c\times a}{a\bullet (b\times c)}, c' = \frac{a\times b}{a\bullet (b\times c)}$

Now, calculate b x c

$\left[\begin{array}{ccc}i&j&k\\2&3&1\\1&-1&-2\end{array}\right] =$

$a'=\frac{}{\bullet }=\frac{}{-5} =$

Find x. 300 043 00. 083 08 00 02 V3

____ [38]

Answer:

Therefore the value of x is 8 unit.

Step-by-step explanation:

Given:

In Right Angle Triangle ABC

angle B = 90°

angle C = 30°

AB = 4

To Find:

AC = Hypotenuse = ?

Solution:

In Right Angle Triangle ABC Sine Identity we have

$\sin C = \frac{\textrm{side opposite to angle C}}{Hypotenuse}\\$

Substituting the given values we get

$\sin 30 = \frac{AB}{AC}$

$\dfrac{1}{2} =\dfrac{4}{x}\\\\\therefore x=4\times 2=8\\\\\therefore x =8$

Therefore the value of x is 8 unit.
