The triangles shown are similar. Find MV.

Mnenie [13.5K]

Answer:

9 units

Step-by-step explanation:

The complete question in the attached figure

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional

so

$\frac{MT}{CS}=\frac{MV}{CI}$

substitute the given values

$\frac{3}{2}=\frac{MV}{6}$

solve for MV

Multiply in cross

$2MV=3(6)\\MV=9\ units$

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

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

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