|dw:1350754955447:dw|

anonymous · Answer

If that angle is 90 degrees, then you should use the pythagorean theorem of right triangles to find x.

anonymous · Answer

Using the Pythagorean theorem in a right triangle, the hypotenuse squared is equal to the sum of the squares of the remaining sides. In your case, A=21, B=13, and C=x. Pythagorean Theorem states $$A^2+B^2=C^2$$.

anonymous · Answer

a^2+b^2=c^2

anonymous · Answer

$$21^{2} + 13^{2} = z^{2}$$ by pythagorean theorem

anonymous · Answer

oh okay guys got it
