Mathematics

Alexxx [7]3 years ago
4 0

Let's solve for x using trigonometric relation ( Cos )

we know,

\cos(30 \degree)  =  \dfrac{base}{hypotenuse}  =   \dfrac{ \sqrt{3} }{2}

now

\dfrac{x}{8}  =  \dfrac{ \sqrt{3} }{2}

x =  8 \times \dfrac{ \sqrt{3} }{2}

x = 4 \sqrt{3}

hence, the value of x is 4 \sqrt{3}
