Answer:
or 12.12
Step-by-step explanation:
The pythagorean theorem states that <em>a</em>^2 + <em>b</em>^2 = <em>c</em>^2, with<em> a</em> and <em>b</em> representing the legs and <em>c</em> representing the hypotenuse.
7^2 + x^2 = 14^2
49 + x^2 = 196
x^2 = 147
x = or 12.12
x = sqrt(147)
This is a right triangle, so we can use the Pythagorean theorem.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.
x^2 +7^2 = 14^2
x^2 +49 = 196
Subtract 49 from each side
Take the square root of each side
sqrt(x^2) = sqrt(147)
