Question

Circles M and K are congruent, QR ≅ LN and OP ≅ VW . Find y.

Answer 1

QR ≅ LN:
-2x = -3y + 15

OP ≅VW:
-6y + 18 = -6x

Solve the second equation for y in terms of x:

-6y = -6x - 18
y = x + 3

Substitute this into the first equation:

-2x = -3(x+3) + 15
-2x = -3x - 9 + 15
x = 6

I hope this helps? :P
