Two of the side lengths of a triangle are 8 centimeters and 40−−√ centimeters. Select the possible lengths of the third side that make the triangle a right triangle.

Step-by-step explanation:

We are given the following in the question:

Two sides of triangle:

8 cm and cm

Let the third side be x cm.

Pythagoras theorem:

The sum of square of two sides of a right angled triangle is equal to the square of hypotenuse.

If the third side is hypotenuse, then by Pythagoras theorem:

If the third side is not hypotenuse, then

Thus, possible third side of triangle are

207/8 is the right

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
