Answer 1

Step-by-step explanation:

ABCD us a cylic quadilateral because all its vertex are on circumference of circle

given,

A=x+10

B=2x+4

C=4y-4

D=5y+5

we know that in cylic quad sum of opposite

angle is equal to 180°

so,

A+D=180

x+10+5y+5=180

x+5y= 165

again

B+C= 180

2x+4+4y-4=180

2x+4y= 180

x+2y= 90

on subtracting both eq we get

(x+5y)-(x+2y)=165-90

3y= 75

y= 25

x+2y=90

x+50=90

x= 40

hence value of x and y be 40 and 25 respectively
