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.
