Respuesta :

You can do part a using The Pythagoras theorem:-

30^2 = x^2 + 24^2

x^2 = 30^2 - 14^2 = (30+24)(30-24) =  324

x =  18
Once you find x using the Pythagorean therom now determine your nagle values

sin = Opposite Side  / Hypotenuse
cosin = Adjacent Side / Hypotenuse
tangent = Opposite Side / Adjacent Side
