Which of the following statements is not true? O The Cosine Rule expresses a relationship between all sides of a triangle and any one of the angles. The Sine Rule expresses a relationship between the lengths of any two sides of a triangle and their opposite angles. Pythagoras's Theorem only holds for right-angled triangles. O The Cosine Rule holds for all triangles. O The Sine Rule only holds for right-angled triangles.

Suppose ABC is a right triangle with sides a, b, and c and right angle at C. Use the Pythagorean theorem to find the unknown side length. Then find the values of the six trigonometric functions for angle B. Rationalize the denominators when applicable. a=7,b=24 What is the length of side c?
