Question

In the given figure, ABCD is a parallelogram. If angle ADC=52°.What will be the value of angle AEC

Answer 1

Answer:

provide Diagram or Explain more clearly what is point E or where the angle AEC formed in parallelogram

Answer 2

Given, ABCD is a parallelogram, ABCE is a cyclic quadrilateral and ADC = 52°

To find: The measure of AEC

Here,

ABC = ADC {Being the opposite angles of a parallelogram}

52°

ABC + AEC = 180° {Being opposite angles of a cyclic quardrilateral)

or, 52° + AEC = 180°

or, AEC 180° - 52°

or, AEC 128°.
