In rectangle KLMN, KM = 8x+20 and LN = 52. Find the value of x. %0D%0A%0D%0A%0D%0A%0D%0A(2 points)

Since KLMN is a rectangle, KM must be equal to LN.

Therefore, we have the equation:
8x + 20 = 52
Subtracting 20 from both sides gives us:
8x = 32
Dividing both sides by 8 gives us the value of x:
x = 4.
