I've seen this monster before on Brainly. I can't imagine it being solved any way but by graphing it.  I'm sure you see the complexity of it with double angle formulas and and then a break down of Cos2x and Sin2x on the right. I'm going to go to desmos and see what it will do. Maybe I can find a way to at least get an answer. And here it is. Blue is the cos function Black is the sign. The sin and cos functions are plotting in degrees, but I don't seem to be able get the x axis in pure degrees. I'm wondering if this is a good enough answer. The other student had much much simpler questions to answer, so I think graphing it is a legitimate result.

Answer:

I hope this helps

Step-by-step explanation:

This is not the same exact question but it shows you the throw down.

A+B+C= 180

so if A=60 and B=70

The sin is= 8

so 60+70= 130

130+c=180

130-180= 50

C=50

Darina [25.2K]
So there is 75 boxes of 12 right? You would figure out how much sticks you have by multiplying then you have to give them to 23 teachers. You take the total of sticks and divide among each teacher 

I hope this helps :)
