Answer:


x=3√(5)

Explanation:

Right Triangles

Right triangles have one of its interior angles with a measure of 90°.

In right triangles the Pythagora's Theorem is satisfied.

Being c the longest side (hypotenuse), a and b the shorter sides (the legs), then:


c^2=a^2+b^2

We have modified the image to include some known data. Both triangles are congruent since they share one side, have a right angle, and have the same base length.

This means the value of x can be calculated as the hypotenuse of the triangle 3-6-x:


x^2=3^2+6^2=9+36=45


x=√(45)=√(9*5)


\boxed{x=3√(5)}
