Question

LAST ATTEMPT IM MARKING AS BRAINLIEST!! ( Pythagorean theorem )

Answer 1

Answer:

x=sqrt(7)

Step-by-step explanation:

Since this is a right triangle, 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 + ( sqrt(7))^2 = (sqrt(14))^2

x^2+7 = 14

x^2 = 14-7

x^2 = 7

Take the square root of each side

sqrt(x^2) = sqrt(7)

x=sqrt(7)

Answer 2

ANSWER:       $x^{2} =(\sqrt{14} )^{2} -(\sqrt{7} )^{2}=42=> x = \sqrt{42}$

Ok done. Thank to me :>
