In rectangle ABED, AC = 7 cm and DE = 10 cm. What is the length of AD? If necessary, round your answer to the nearest tenth.
Where is C in rectangle ABED?
the center. its a rectangle broken into the triangles
CE must be 7 also, as C bisects AE.You have a right triangle AED, so AE=14 (hypotenuse), side DE 10.
