Answer:
8
Step-by-step explanation:
all numbers must be positive when you have the lines on the side
OL is perpendicular to ON, which means that there is a 90 degree angle being created between these two line segments. So, angle LON is equal to 90 degrees. Because LON is a 90 degree angle and we have two angles within it, those two angles are complimentary. We can add LOM and MON together and they will equal 90 degrees.
3x - 15 + 5x - 23 = 90
8x - 38 = 90
8x = 128
x = 16 degrees
Angle MON = 5x - 23
5(16) - 23 = 57 degrees
Angle MON = 57 degrees

18*4 = 72 (finding the area of the rectangle)
72/2 = 36 (finding the area of the square)
√36 = 6 (finding one side of the square)
6*4 = 24 (finding the perimeter)
The perimeter is 24in,
Hope this helps! :)
