Answer:
1=110 degrees given
2=70 degrees
3=80 degrees
4=100 degrees
Step-by-step explanation:
1=110
2=180-110=70
3=1/2(100+60)=80 by the angle formed by two chords theorem
4=1/2(80+120)=100 by the angle formed by two chords theorem

To find increasing and decreasing intervals we take derivative
Now we set the derivative =0 and solve for x
sinx + cosx =0
divide whole equation by cos x

tanx +1 =0
tanx = 1
and
Now we pick a number between 0 to 
Lets pick 
Plug it into the derivative
= 4.810 is positive
So the graph of f(x) is increasing on the interval [0,
)
Now we pick a number between
to 2pi
Lets pick 
Plug it into the derivative
= 116 is positive
So the graph of f(x) is increasing on the interval 
Increasing interval is 
Decreasing interval is 
(b)
The graph of f(x) increases and reaches a local maximum at 
The graph of f(x) decreases and reaches a local minimum at 
(c)
f(0) = 0



Here global maximum at 
Here global minimum at
