Question

Find the length of side x in simplest radical form with a rational denominator

Answer 1

The answer is "
`(7√(3))/(2)`"

Explanation:

`\to \sin 60^(\circ) = (x)/(7) \\\\\to x=\sin 60^(\circ) * 7 \\\\\therefore \sin 60^(\circ) = (√(3))/(2) \\\\\to x= (√(3))/(2)* 7 \\\\\to x= (7√(3))/(2)`
