Answer:

Step-by-step explanation:
So we have the equation:

And we want to solve for R.
First, let's multiply both sides by J to remove the fraction on the right. So:

Simplify the right:

We can rewrite our equation as:

So, to isolate the R variable, divide both sides by I²t:

The right side cancels, so:

And we are done!
Answer:
210°
Step-by-step explanation:
Given
sinΘ = - 
Note taken the inverse sine of the positive value of the ratio, gives the related acute angle, that is
Θ =
(
) = 30° ← related acute angle
Thus the required angle in the third quadrant is
Θ = 180° + 30° = 210°
