Answer 1

Answer:x=40°

Step-by-step explanation:now , let the angle holding 4x -64° =D

Now, angle D + angle A =180°

(Because they are opposite angles of a CYCLIC quadilateral SUM up to 180° )

Therefore ;

2x + 4° + 4x -64° = 180°

= 6x - 60° = 180°

= 6x = 180° + 60°

= 6x = 240°

= x = 240°/6

= x = 40°

HENCE- X = 40°
