What is Sine ?
"In a right angled triangle, the sine of an angle is:
The length of the side opposite the angle divided by the length of the hypotenuse.
The abbreviation is sin
sin θ = opposite / hypotenuse"
Here,
Perpendicular of the triangle is = 9
and the adjacent angle is = 39°
[tex]sin(39°) = perpendicular/ hypotenuse = 9/x\\x = 9/ 0.629 = 14.30[/tex]
Hence, the value of x is 14.30
