So,

You'll need to use a reference sheet or the unit circle to determine the value of cos(30). Or you could use a 30-60-90 triangle template.
When using the unit circle, look in the upper right quadrant (which is quadrant 1). The angle 30 degrees is in this quadrant. Locate the terminal point and note how

Answer:
The second map is larger in size
Step-by-step explanation:
Map 1 = scale of 1 inch to 100
Map 2= scale of 1 inch to 500
Lets assume, the parks have a length of 3000 ft and a width of 2000ft.
Map 1
Length = 3000/1000 = 3ft
Width = 2000/1000 = 2 ft
Map 2
Length: 3000/500 = 6 ft
Wdght: 2000/500 = 4ft
In both length and width, second map is larger in size.
