You need to be PATIENT and wait for a math tutor to come online. Currently, I don't see any of them online.

Since there is no diagram available here, it's hard to see just where D and E are. I can visualize a large right triangle ABC, but I'm not sure where the smaller triangle ADE is located.

here is the diagram Steve but it is not perfect.
All sides are in cm. there r no dotted lines, but i didn't had any choice.
