Question

In a right –angled triangle, the length of hypotenuse and shorter sides are 13 cm and 5 cm respectively. Work out the other side.

Answer 1

Answer: The other side is 12 cm.

Step-by-step explanation:

• $a^{2} + b^{2} = c^{2}$
• $a^{2} + (5)^{2} = (13)^{2}$
• $a^{2} + 25 = 169$
• $a^{2} = 144$
• $a = \sqrt{144}$
• $a = 12$
