Remark
This is just a calculator problem. Look around on your calculator for the sin button
Above it you will find something like sin-1. that will give you the answer.
Here's how you do it with most calculators.

Answer:
18
Step-by-step explanation:
Adding 6 and 3 gives you the full length of the long side of rectangle and since 3 is the radius of the circle, the short side if the rectangle would also be equal to 3.
So, the long sides equal 9 and the short sides are 3, making the perimeter 18
Answer:
60°
Step-by-step explanation:
Let angle BAE = angle ACD = x
BCD = AEC = 60°
EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°
EAC = 60° - x
BAC = EAC + BAE = 60° - x + x = 60°
