First: there can only be one hypotenuse in a right angled triangle and it is always OPPOSITE the right angle, NEVER adjacent.

Yes.
When considering an angle in a right angled triangle, the adjacent is the short side next to the angle and the hypotenuse is the long one (which will be opposite the right angle)
In a right angle triangle the adjacent angle is at the base of the hypotenuse and next to the right angle
That's the cosine of the angle to which the 'adjacent' side is adjacent.
The sine of an angle in a right triangle is opposite/hypotenuse, where opposite is the only side that is not adjacent to the angle you want to find the sine of, and the hypotenuse is the side opposite the right angle in the triangle. Just find opposite/hypotenuse.
