Question

What is the value of x? If necessary, round your answer to two decimal places. ( Picture attached below )

Answer 1

use the pythagorean theorem :
x^2 = 24^2 - 12^2
solve for x

Answer 2

Pythagorean Theorem: a^2 + b^2 = c^2

In this case, you have the hypotenuse and the height

so you can fill in it as: 12^2 + b^2 = 24^2

*b is the same thing as x

and you can just solve for the missing variable by squaring the numbers and moving 12^2 over to the right side by subtracting it.

Voila! the answer!

Answer 3

@swin2013 So 24^2=576, 12^2=144, 576-144=432 but whats the square root?
