Answer: The width is the square root of 40 or 6.32
Step-by-step explanation:
9^2 + b^2 = 11^2 where b squared is the width
81 + b^2 = 121
-81 -81
b^2 = 40
b= 6.32
90/2 = 45 degrees twices
These both are 45 degrees which is less than 90
So the total is 120. You want 1/6 of those.
So do (1/6)*120
You get 20.
YAY
