When the lines are parallel and angles are given, and since a straight line is 180°, the 2 angles of the line intersecting the parallel lines have to add up to be 180. Therefore,
21. 31°
22. 96°
23. 149°
24. 84°
25. 53°

I'm going to refer to the length of the pool as L.
2x + 2L = perimeter.
The width of pool multiplied by two added to the length of the pool multiplied by two equals to the perimeter.
Find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve
