Answer: x = 2
Step-by-step explanation:
The diagram of the kite is shown in the attached photo.
The perimeter of the kite is the distance around the kite.
The kite has 2 pairs of equal sides.
This means that
Side ML = side MN and side NO =
side LO
If Side MN = 8x – 3 and side NO = 2x + 1, then The perimeter of the kite is ML + MN + NO + LO
The perimeter of kite LMNO is given as 36 feet.
Therefore
ML + MN + NO + LO = 36
8x – 3 + 2x + 1 +8x – 3 + 2x + 1 = 36
8x + 8x + 2x+ 2x -3 +1 - 3 + 1
20x -4 = 36
20x = 40
x = 40/20 = 2
