Answer:
S=49
Step-by-step explanation:
Any triangle has an interior angle of 180.
So just add them up and set the sum equal to 180 degrees.
2s+s+33=180
3s=180-33
3s=147 .   Divide both sides by 3 to isolate variable s
s=49

I believe your mistake is that you are trying to use the sector area formula ti find arc length when there is already a formula for it.
The formula for it is 

So first substitute the values in and then simplify!

Now simplify!
21 × 118 is 2478 so it's 

When divided ou and multiplied, this is 21.62cm!
 
        
        
        
Answer:
Step-by-step explanation:
f(x)=4x+1
g(x) = x^2-5
(f*g)(x) = 4x^3+x^2-20x-5
