A right-angled triangle has side lengths of 8.65cm and 10.15cm. What is the length of its hypotenuse?
Step 1: Draw a labelled diagram of the triangle, marking the side lengths. Step 2: Recall Pythagoras’ theorem equation ‘c2=a2+b2’ Step 3: Substitute the values of a and b into the equation. c2=8.652+10.152 Step 4: Solve the equation. c2=117.845 Step 5: Find c by square-rooting both sides of the equation. c=13.3358…cm
