In the circle below, ∡DAB and ∡DCB are right angles and m∡BDC = 53°. The figure is not drawn to scale.
A circle is shown with two inscribed right triangles that both share the diameter upper D upper B as their longest side. Point upper A and point upper C are equal distance above and below upper D so that triangle upper A upper D upper B and triangle upper C upper D upper B are both right triangles.
What is lower m modifying above upper C upper A upper D with arc?
(1 point)
