Answer 1

Answer:

x is 35 degrees

y is 110 degrees

Step-by-step explanation:

(y+20) + 50 = 180 degrees

since opposite angles in a cyclic quadrilateral is 180 degrees

that is PQR + PSR = 180

so y+ 70 = 180

or y = 110 degrees

Also

QPS + QRS = 180 degrees ( same as above i.e opposite angles in a cyclic quadrilateral is 180 degrees)

So 2x+y = 180

we know y is 110

so 2x + 110 is 180

therefore 2x = 70

=> x = 35 degrees

hope it helps you...

Answer 2

Answer:

As we know the sum of opposite angles of cyclic quad. Is 180 then taking angle Q and angle S

Y+20+50=180.

Y=110..

Now taking P and R

2x+Y=180..(we know that Y=110 so

2x+110=180

X=35...
