-- Opposite angles of a parallelogram are equal, so 2x+19 = 3x.
Solve this, and you'll know what 'x' is.
-- Adjacent angles of a parallelogram are supplementary, so y+3x = 180.
You know what 'x' is, so you can solve this one and find 'y'.
so the ice rink diameter is 80 feet what mean that the radius of ice rink is 40 feet
the walkway is 10 feet wide
so 10+40=50 what mean that the radius and the walkway wide make 50 feet length together
using this length area = pi*r^2 = 3,14*(50)^2 = 7850 feet squared
area of ice rink = 3,14*40^2 = 5024 feet squared
area of the walkway = 7850-5024 = 2826 feet squared
hope helped
Answer:
y-5=-1/2(x+3)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-5)/(-1-(-3))
m=-1/(-1+3)
m=-1/2
y-y1=m(x-x1)
y-5=-1/2(x-(-3))
y-5=-1/2(x+3)
common denumerator is 12
-8/12x-9/12x=10/12
-17/12x=10/12 <<multiply by 12
-17x=10
x=-0.59
Answer:

is my answer correct?
im pretty sure it is...
what is the 4.7cm the radius or circumference
if its the circumferance the answer is 1.753
