Best ResponseYou've already chosen the best response.0Well, you know two sides of the inner right triangle BCD and AD. You could use Pythagorean theorem to find the third side of the first triangle, and that's one segment of the leg in the larger right triangle. Then just add them together and use Pythagorean theorem again...
