Question

I will give u brain thing its urgent!!!!!​

Answer 1

Assuming this is a right triangle, we can use the Pythagorean theorem:

$(length-of-leg-1)^2+(length-of-leg-2)^2=(length-of-hypotenuse)^2\\12^2 + 7^2 = (length-of-hypotenuse)^2\\193 = (length-of-hypotenuse)^2\\length-of-hypotenuse = \sqrt{193}$

Thus x = $\sqrt{193}$

Hope that helped!
