Question

If one leg of a right triangle is 8 mm and the other leg is 5 mm, what is the approximate length of the hypotenuse of the triangle? round your answer to the nearest whole.

Answer 1

The formula to calculate the missing side of a triangle is the Pythagorean theorem:

c² = a² + b²

In your case, c will be the hypotenuse:


`c^(2) = 8^(2) + 5^(2)`

`c^(2) = 64 + 25`

`c^(2) = 89`

`c = √(89)`

`c = 9,43`

The answer is 9mm.

Hope it helped!

Answer 2

Answer: 9 mm

Step-by-step explanation:

a² + b² = c²
8² + 5² = c²
c² = 64 + 25
c² = 89
c= √89
c = 9 mm (nearest whole number)
