Answer: The answer is actually non of the above, y and z are not acute, they are higher that 90 degree angles. x is an 90 degree angle. so x=90 y=142 z=128
Step-by-step explanation:
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

If the two young men practiced the piano 11 but Jeff practiced the piano 3 more hours its a simple answer
We proceed to graph the points and verify which is within the shaded area
so
points B and D are not within the shaded area
point C is not a solution because it is in the limit and the limits are not included
point A is inside the shaded area
therefore
the answer is
the point A
see the attached figure
The correct one is bottom left
