What does it mean if the sine of an angle is ¾?

The side of the triangle next to the angle is ¾ as long as the hypotenuse.

The hypotenuse is ¾ as long as the side of the triangle next to the angle.

The side of the triangle opposite the angle is ¾ as long as the hypotenuse.

The hypotenuse is ¾ as long as the side of the triangle opposite the angle.

Why can’t the cosine of an angle be greater than 1?

The side next to the angle cannot be longer than the hypotenuse.

The hypotenuse cannot be longer than the side next to the angle.

The side opposite the angle cannot be longer than the hypotenuse.

The hypotenuse cannot be longer than the side opposite the angle.
