15 points

x is 5

Using Pythagoras' theorem

side² = hyp² – side²

x² = 13² – 12²

x² = 169 – 144

x² = 25

x = √25

x = 5

x=5

Step-by-step explanation:

x^2 + 12^2 = 13^2

x^2 +144 = 169

x^2 = 25

x=5

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.
