Question

Please answer this with explanation! ​

Answer 1

Answer:

(a) 120

Step-by-step explanation:

as the opposite angles in a cyclic quadrilateral are supplementary. Therefore , 60 +x =180

180-60=120

Answer 2

Answer:

120

because any two points (here p and q) makes an angle on circumference (I.e.60) it will be half of the angle made at center.

so angle made by p and q at the center is double the angle made at the circumference by the two same points.
