Question

3. The hypotenuse of a right triangle is 13 cm long. If one of the remaining
two sides of length 5 cm. Find the length of another side.​

Answer 1

Answer:

The answer is 12 cm by PGT

Answer 2

Answer:

length of the other side equals 12cm

Step-by-step explanation:

let we take hypotenuse is AC.

Other two sides are AB and BC

By Pythagoras theorem

we have AC² = AB² + BC²

${13}^{2} = {5}^{2} + {bc}^{2} \\ {bc}^{2} = {13}^{2} - {5}^{2} \\ = 169 - 25 \\ = 144 \\ {bc}^{2} = 144 \\ \sqrt{ {bc}^{2} } = \sqrt{144} \\ bc = \: \sqrt{12 \times 12} = 12 \\ bc = 12cm$
