Question

Please help i don’t understand what so ever

Answer 1

6

Explanation:

By Pythagoras theorem

10^2 = 8^2 + x^2

100= 64 + x^2

X^2 =100-64

X^2= 36

`x = √(36) \\ x = 6`

Hope this helps..

Answer 2

x=6

Explanation:

Because of the Pythagorean theorem, you know that the square of the two legs of a right triangle will be equal to the square of the hypotenuse. Conversely, the square of one of the legs will be equal to the square of the other leg subtracted from the square of the hypotenuse. Therefore:

`x^2=10^2-8^2 \\\\x^2=100-64\\\\x^2=36\\\\x=6`

Hope this helps!
