Question

What is the approximate length of the missing side of a

right triangle with hypotenuse of 16 cm and other side of
15 cm?

Answer 1

The approximate length of the missing side is of 5.57 cm.

Explanation:

Pythagorean Theorem:

In a right triangle with sides a and b and hypotenuse c, the Pythagorean theorem states that:

`a^2 + b^2 = c^2`

In this question:

`a = 15, c = 16`

We want to find b. Then

`a^2 + b^2 = c^2`

`15^2 + b^2 = 16^2`

`b^2 = 256 - 225`

`b^2 = 31`

`b = √(31)`

`b = 5.57`

The approximate length of the missing side is of 5.57 cm.
