In a circle, ABCD is a cyclic quardilateral. Ac and Bd intersect each other at P. If AB and ∠BAC = 38°, then the measure of ∠ADC is
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e.114°
If AB = AC, then triangle ABC is an isosceles triangle.
If angle(BAC) = 38°
Then, angle(ABC) = angle(BCA) = 66°
In a cyclic quadrilateral, The sum of opposite angles is 180
If angle(ABC) = 66° , then angle(ADC) = 114°
