Isosceles trapezoid ABCD contains inscribed circle o. The area of the trapezoid is 510 square centimeters. The radius of the circle is 10 cm. Find AD.

Question

Its a gemotry type of question, to find the angle AD using the above information. I cannot exactly get it, their must be a way to solve it. If someone could help me, get the answer that would be amazing! Thanks!

Answer 1

Try taking a photo of the figure and the problem and posting a link to it. Geometry is difficult without a reference. Also angles use 3 points to describe them, AD would be a line or line segment.
