Answer:
x = 45, y = 36.
Step-by-step explanation:
We can see that JK is similar to MN, so the ratio of the lengths is 54 : 42 or 9 : 7, so we can multiply 28 by 9/7 to get y, and 35 by 9/7 to get x.
y = 28 x 9 / 7 = 36
x = 35 x 9 / 7 = 45
The answer is x = 45, and y = 36, so you were correct.
Also, the reason IK is similar to ML and IJ to NL is because we can see that y is a bit shorter than x, and ML is a bit shorter than LN.
