A right-angle triangle has three sides (diagram would be included). Side A = 3cm; Side B = 7cm. What is the length of Side C (the hypotenuse)? Give your answer to 2 d.p.

Using Pythagoras' Theorem --> a2+ b2 = c2 (or c = SqRT(a2 + b2)) where c is the hypotenuse.Substitute a = 3; b = 7. So: 32 + 72 = c29 + 49 = 58. SqRt(58) = 7.62. Side C = 7.62 cm
