Answer 2

$\huge \mathrm \color{red}{ \underline {\underline{Question}}}$

The distance between the points (aSin60° , 0) and (0 , aCos30°) is

$1) - \sqrt{ \frac{3}{2} } a \\ 2) - \sqrt{ \frac{2}{3} } a \\ 3) \sqrt{ \frac{3}{2} } |a| \\ 4) \sqrt{ \frac{2}{3} } |a|$

We know that

$Sin60° = \frac{ \sqrt{3} }{2} = Cos30°$

Distance from origin = √(x² + y²)

$x = aSin60° = \frac{ \sqrt{3} }{2} a$

$y= aCos30° = \frac{ \sqrt{3} }{2} a$

$= \sqrt{ {( \frac{ \sqrt{3} }{2}a)}^{2} + {( \frac{ \sqrt{3} }{2}a)}^{2} } = \sqrt{ \frac{3}{4} {a}^{2} + \frac{3}{4} {a}^{2}}$
