Answer 1

Answer:

x=12

Step-by-step explanation:

x²+9²= 15² ---by Pythagoras theorem

x²= 15²-9²

x²= 225-81

x²=144

x²=12²

x=12

The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Answer 2

Answer:

$the \: \: answer \: is \: x \: = 12$

Step-by-step explanation:

By pythagoras theorem

AC^2 = AB ^2 + BC ^2

15^2 = x^2 + 9^2

225 = x^2 + 81

x^2 = 225 – 81

x^2 = 144

$x = \sqrt{144}$

$x = 12$

Hope it helps you dude.

Have a great day.
