Best ResponseYou've already chosen the best response.0In any right triangle, you can use the Pythagorean Therom to solve for sides. In that triangle, x is 2 of the sides and equals 3. Pyhtagreons Therom is a^2+b^2=c^2 A and b are the x's in the diagram. So 3^2 + 3^2 is equal to 18= c^2 Then find the square root of 18 to solve.
