**MathMate**, Tuesday, April 19, 2011 at 1:42pmIf the triangle had sides 7 and 24 adjacent to the right angle, then the hypothenuse is sqrt(7^2+24^2)=25 by Pythagoras theorem.

The sin of angle θ adjacent to the side 7 has an opposite side of 24 over the hypothenuse of 25, so

sin(θ)=24/25.

Similarly, the sin of the angle φ is the opposite side 7 divided by the hypothenuse of 25 to give 7/25.
