Question

Need to know what the value of x is

Answer 1

Use the Pythagorean Theorem

x^2 = 9^2 + 12^2

x^2 = 81 + 144

x^2 = 225

x = 15

Explanation:

Answer 2

`x=15`

Explanation:

Use the Pythagorean Theorem

`a^2-b^2=c^2`

With c being the hypotenuse, or x in this case

`9^2+12^2=x^2`

`81+144=x^2`

`225=x^2`

Now take the square root of 225

`√(225)=x`

`√(225)=15`

`x=15`
