Is this the sqrt root of ((1.16x10^-19)^2)
The opposite of -1/2 is 1/2. If you put -1/2 in absolute value, then the answer is 1/2.
I think the answer is 80 degrees. Think about it like you're moving the chunk with 100 degrees already filled in, to the space where you're trying to find the amount since they're the same. Vertical angles are supplementary and are equal to 180. So, 100+x = 180. x would equal 80 degrees.
