Question

plz.. tell me the answer of my question​

Answer 1

Answer:

solution

Step-by-step explanation:

We know that angle by the same arc at circle i.e., on the

circumference is half of the angle by the same arc at the center.

angleX = 1/2 x 160° = 80°

(Opposite triangles of a cyclic quadrilateral supplementary)

angle X + angle y = 180°

.: 2y = 100°

.: 3angle y - 22x

= 3 x 100° -

= 300° - 160°

(Opposite triangles of a cyclic

quadrilateral supplementary)

+ xy = 180°

.: 2y = 100°

.: 3angle y - 2angle x

= 3 x 100° - 2 x 80° =

= 300° - 160° =

= 140°.

hope this will help you
