The hypotenuse of a right angle triangle is 13cm. if one other side of the triangle is 1cm shorter than the hypotenuse. calculate the third scale of the triangle

Find the third scale of the triangle .

Let the third Side be x.

According to the question,

★ Hypotenuse = 13 cm

★ Other side = Hypotenuse - 1 [ Given ]

= 13 cm - 1 cm

= 12 cm

Now,

By pythagoras theorem,

13² = 12² + x²

⇒ 169 = 144 + x²

⇒ x² = 169 - 144

⇒ x² = 25

⇒ x = √25

⇒ x = 5 cm

Hence, the third scale of the triangle is 5 cm.

answer: 40.95
