2. Trapezoid ABCD has bases line AB and line CD. abcd is an isosceles trapezoid with legs AB and CD and base BC. If the length of AB is 7y-4, the length of BC s 4y-6 and the length of CD is 8y-18, find the value of y. 30 points for brainliest! geometry. Solve for x, given that ABCD is an isosceles trapezoid, AC = 2x + 12, and BD = 4x - 30. Geometry . Quadrilateral ABCD is a parallelogram. The diagram shows —. AE ≅ —. Find the perimeter and area of each of the following figures. find AE and EC. Suppose isosceles trapezoid ABCD has AD = BC = 13, AB = 10, and DC = 22. inches was erected in a stadium. Find the measure of the diagonal of the HD display.

Height, midsegment, area of a trapezoid and angle between the diagonals 3. Height, sides and angle at the base 4. Using the law of cosines In the diagram below, ABCE is an isosceles trapezoid. Point D lies on line CE so that AE is parallel to BD and angle CBD=28 degrees Find angle BAE in degrees. 2. Trapezoid ABCD has bases line AB and line CD. abcd is an isosceles trapezoid with legs AB and CD and base BC. If the length of AB is 7y-4, the length of BC s 4y-6 and the length of CD is 8y-18, find the value of y.

in view The median joins the midpoints of AD and CB. It's formula is 1/2 * (5 + 15) = 10 for its length. If the trapezoid is isosceles, then Odla solros inomhus

Find the Example: Given isosceles trapezoid ABCD with AB I CD, AB = 4, CD = 14, and AD = 13. Trapezoid ABCD.PNG The height of isosceles trapezoid ABDC is 12 units. The length ED^2+AE^2=AD^2 -->ED^2+12^2=15^2 --> ED=9. Now, as the Imagine this as the one attached below and then find the area of rectangle. 12*9 = 108 Determine whether ABCD is an isosceles trapezoid. Explain.
