Question

What is the value of x?!​

Answer 1

5
`√(3)`

Explanation:

Using the sine ratio in the right triangle and the exact value of

sin60° =
`(√(3) )/(2)`, then

sin60° =
`(opposite)/(hypotenuse)` =
`(x)/(10)`

Multiply both sides by 10

10 × sin60° = x

10 ×
`(√(3) )/(2)`, hence

x = 5
`√(3)`
