Answer:

Step-by-step explanation:
The explanation is in the picture!❤
Check the picture below.
make sure your calculator is in Radian mode, since the angle is in radians.
in case you're wondering, in the Unit Circle, the radius is 1, and due to that, the arc's length, in this case an arc of 2 units, is the same value as the angle it makes in radians, so, if the arc is 2, then the angle it makes, in this case clockwise, in the direction as a clock moves, or a negative angle of -2 radians then.
How to do these problems.
Here we have a multiplication equation where we multiply fractions.
For example:
1/2*5/7. The answer is 1*5/2*7. Basically multiply the two numbers in the top row and the 2 numbers in the bottom row. Simplify the fraction if needed.
Divide both sides by <span>t

<span>a+b=r/t
</span>Subtract b <span>from both sides
</span>
a<span>=r/t-b = Solution </span>
