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

Find x.<br> 300<br> 043<br> 00.<br> 083<br> 08<br> 00<br> 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.
