First, and most important, you must know what the question is. You haven't told us what the question is, and a gray cloud hangs like a dark mist over the problem, giving the unmistakable impression that you're not too sure of it yourself.
Answer:
a quadrilateral adds up to 360 degrees so each 4 siede figure is 360 degress
Step-by-step explanation:
1. add 108 + 59 + 119= 286 now do 360 - 286 = and you get 74
so that is how you get the answeres for the question , add the degrees then minus it by 360

2. x = 234
3. x = 37
4. x = 83
We know that sin2x=2sinxcosx
(search the net for proof if you wish)
So the original equation becomes
2sinxcosx-sinx=0
The two terms both have sinx that can be taken out to get:
sinx(2cosx-1)=0
This is true if sinx=0 or 2cosx-1=0 , rewritten: cosx=1/2
sinx=0 than x=2kπ
cosx=1/2 than x=π/3+2kπ
where k is an integer
