Question

Please find X for me this is Pythagorean theorem

Answer 1

x = 6 *
`√(10)`

Explanation:

I assume x is the diagonal. length

if so here it goes:

the base length is 18

the height of the triangle should be ... 13 - 7 = 6

so hypotenuse = root ( 18^2 + 6^2) = root(324 + 36) = root(360) = 6root(10)
