Step-by-step explanation:
Co terminal angles are angle ± 2π, that is
+ 2π
=
+
= 
and
- 2π
=
-
= - 
X+90 = length
x=width
4x+180=400
4x=220
x=55
The width is 55 yards and the length is 145 yards
Ratio of perimeter (linear measure) is the same as the scale factor (5:6).
Ratio of area (unit squared) is the square of the ratio, namely 5^2:6^2=25:36
Ratio of volume (unit cubed) is the cube of the ratio, namely 5^3:6^3=125:216
