প্রদত্ত চিত্রে চতুর্ভুজ ABCD সীমাবদ্ধ এবং AD_|_DC। বৃত্তের ব্যাসার্ধ হলে x খুঁজুন...

If AB||DC and AD||BC Find the value of x and y

In trapezium ABCD, AB || DC AB=16cm, DC=10cm, AD=CB=5cm then its area is cm^2.

A cyclic quadrailatral ABCD is such that AB=BC, AD=Dc AC _|_ BD, angle CAD = theta Then the angle angle ABC

In the above figure there is an incircle in quadrilateral ABCD. BC = 38 cm, QB = 27 cm, DC = 25 cm and AD _|_ DC. What is the radius of the circle?

A cyclic quadrilateral ABCD is such that AB=BC,AD=DC and AC and BD intersect at O. If angleCAD=46^@ , then the measure of angleAOB is equal to:

In a cyclic quadrilateral ABCD, AB = BC, AD = DC, AC_|_BD, angleCAD=theta . Then angleABC will be-

In the figure Delta ABC, DE||AB . If AD = 2x, DC = x + 3, BE = 2x - 1 CE = x then find the value of x .
