Find x. \/3 1.5 3 \/3 2

serg [7]

$x = \sqrt{3}$

Step-by-step explanation:

Given:

$\sin(ABC) = \frac{AC}{AB}$

$= > \sin(60) = \frac{3}{AB}$

$= >AB= 2 \sqrt{3}$

Now by Pythagoras theorem,

$AC^{2} + BC^{2} = AB^{2}$

Substituting values,

${3}^{2} + {x}^{2} = (2 \sqrt{3})^{2}$

$= > {x} = \sqrt{3}$

Hence, value of x is $\sqrt{3}$
