yeah I have some solve for x leave your answer in simplest radical form

The image above gives a better analysis of the image in the question
To get x, we will make use of the Pythagoras theorem.
since x is the hypotenuse
[tex]x^2=4^2+2^2[/tex][tex]x^2\text{ = 16 + 4}[/tex][tex]x^2\text{ = }\sqrt[]{20}[/tex][tex]x\text{ = }\sqrt[]{4\text{ x 5}}[/tex][tex]x\text{ =}\sqrt[]{4}\text{ x}\sqrt[]{5}[/tex][tex]x\text{ = 2 x }\sqrt[]{5}[/tex][tex]x\text{ = 2}\sqrt[]{5}[/tex]In the simplest radical form, x is equal to
[tex]2\sqrt[]{5}[/tex]
