SOMEONE HELP GEOMETRY
ALSO THE LAST ANSWER CHOICE WAS
E. AD is congruent it equal to CD

b? Ac should be Perpendicular to BD Or it might be A, but I'm pretty sure that it's B

Step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )
