Answer:
Sine 60°= √3/2
=1.732/2
0.8660
Explanation:
In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse).
From the triangle shown in the attachment
The sine of an angle =
Opposite/hypotenuse
Sine 60°= √3/2
=1.732/2
0.8660
