Answer 2

Answer:

10.4

Step-by-step explanation:

We can use the Pythagorean theorem to solve for the unknown side since this is a right a triangle.

a^2 +b^2 =c^2

where a and b are the sides and c is the hypotenuse

6^2 + x^2 =12^2

36+x^2 = 144

Subtract 36 from each side

36-26+x^2 =144-36

x^2 =108

Take the square root of each side

sqrt(x^2) = sqrt(108)

x = sqrt(108)

x =10.3923

x =10.4  rounding to the nearest tenth
