In the quadrilateral ABCD, angle A = 90°, angle ABD = 40°, angle BDC = 5°, angle C = 45°, and the length of AB is 6. Find the area of the quadrilateral ABCD.
Quadrilateral ABCD has AD = BC, ∠A + ∠B = 90°, AB = 20, CD = 10, as shown below.
What is the area of ABCD?
Quadrilateral ABCD has the following properties:
Angle B and D are each right angle AB and BC has the same length 1 unit.
What is the area of quadrilateral.
Quadrilateral ABCD has a 90 degree right angle at C and BC = CD = 10 miles. A car is traveling from A to C. If the car takes the path of AC then it takes 30 minutes. If the car takes the path of AB then BC it takes 35 minutes. If the car takes the path of AD and then DC it takes 40 minutes. The car always travels at a constant speed. What is the speed of the car?
Triangle ABC is an isosceles triangle with AB = AC and A = 100°. Extend the ray from A to B until point D such that AD = BC, as shown below. What is the measure of angle BDC?
ABCD is a quadrilateral. Point O is along AD. A semicircle has a diameter along AD and is tangent to the sides AB, BC, and CD. If AB = 9, CD = 16, and AO = OD, what is the length of AD?
