Answer:
Below.
Step-by-step explanation:
sin-1 1/2 = 30 degrees in the first quadrant.
As the sin is negative in Quadrants 3 and 4,
sin01 -1/2
= 210, 330 degrees, in the range 0-360 degrees
To find the area of a square you just do LxW
= 81km
To find the answer ,multiply 2 1/2 by 2/5
(2/5)*(2 1/2)=1
Therefore you should use 1 cup of flour.
