There is a right angled triangle, you know the length of the hypotenuse (6) and one other side (3), can you calculate the third side of the triangle?
So it is easiest if we first draw out the triangle and label it.We use an equation called Pythagoras' Theorem. This equation is A^2 + B^2 = C^2So we know the length of side A (3) and side C (6), lets put this into the formula:3^2 + B^2 = 6^29 + B^2 = 36B^2 = 27B = √27B = 5.20 (2DP)
