Question

find x,y please tell by step by step in circles​

Answer 1

Answer:

y= 90

as Angle DCA is the opp. angle of A 90 degrees

Answer 2

Answer:

x=60°

y= 90°

Step-by-step explanation:

ABCD is a cyclic quadrilateral. In a cyclic quadrilateral, opposite angles are supplementary.

=> ∠B + ∠D =180

= x+2x = 180

= 3x = 180

x = 180/3

∴ x=60°

Similarly, ∠A+∠C= 180

=> 90+∠C=180

∠C = 180-90=90°

Now, ∠C and y are in a linear pair.

=> ∠C + y= 180

y = 180-90=90°

∴ y=90°
