The answer is 11, and I am 100% positive it is the correct answer because I used my calculator and double checked.
Well, we can eliminate the first 2 options as an absolute value of either a positive or negative number will yield a positive number. The absolute value of 0 is 0. This there is only 1 solution for this, and that is 0. The solution would be C.
It can't be D, because in both cases the absolute value of -1 and 1 will be 1 and thus there are 2 solutions, -1 and 1.
Geometry Rule: SOH CAH TOA.
Sine = opposite over hypotenuse
Cosine = adjacent over hypotenuse
Tangent = opposite over hypotenuse
I won't solve all of these for you because I find that solving it on your own is an important step in learning to actually understand how this works.
9 ways. I'm not sure how to show work on this
