The answer is 13, i got this by using the pythagorean theorem. a^2 + b^2 = c^2. in this case it would be 84^2 + b^2 = 85^2. then that would turn into 7056 + b^2 = 7225, subtract both sides by 7056 to get b^2 = 169, then square 169 to get 13 :)

Someone please please help me!!!! i need help!

This one’s pretty easy because it’s a square meaning the corners will always be 90 degrees so if a line splits the 90 it becomes half which is 45. And the reason AEB is 90 is because it’s two top corners are 45 degrees so the last angle must make the whole triangle equal 180 degrees.
DBC=45
AEB=90
