HEY THERE!!

GIVEN :- Circle M and K are congruent and line QR is congruent to LN and line OP is congruent to VW.

TO PROVE :- The value of y

SOLUTION:-As we know if two lines are congruent then there equations will be equall.

1. QR is congruent to LN.

=> - x = y+8..........1️⃣

2. OP is congruent to VW.

=> -x = 3y + 16..........2️⃣

Now as we know circle M and K are congruent

so from equation 1️⃣

x= -y-8 put this value in equation 2️⃣

=> y+8= 3y+16

=> 2y = -8

dividing from two to both sides.

=> y= -4

HOPE IT HELPED YOU.
