What is a Trapezoid?
A trapezoid is a quadrilateral which is having a pair of opposite sides as parallel and the length of the parallel sides is not equal.
In an isosceles trapezoid, the angles formed at the ends of any one of the parallel lines are congruent. Therefore, we can write,
5x+15 =7x-11
15+11=7x-5x
26=2x
x = 13
Hence, the value of x is 13.
