Circumference of a circle is found with the equation
C = 2 × pi × r
where r is the radius. So for your problem...
C = 2 × 3.14 × 4
C = 25.12 meters
Both angles equal 117 so you put both angle equations together and set them equal to 117 then x= -2
Plug the -2 in for the x in both separate equations to get
M< XYW = 32°
M< WYZ = 85°
-7/12=y/-36
times both sides by -36 (-36=12*-3)
-3*-7=y
21=y
y=-21
