Question

In the diagram below, AE = 12, EB = 6, and CE = 4. Find DE

Answer 1

Alright...we have 2 lines that go fully across the circles....these are lines that will be equal in length because of that...

So since we know AE = 12 and then EB = 6 ...then the distance across that whole line A to B would be 12 + 6 = 18

So now...we know CE = 4 ...and we want ED.....but we know the length must be 18....so we have

CE + ED = 18

4 + ED = 18

ED = 18 - 4

ED = ???
