Answer:
I think it's 300
Step-by-step explanation:
 
        
                    
             
        
        
        
Sec(theta) = 1 / cos (theta) = hypotenuse / x -coordinate
hypotenuse = 1 (because it is the radius of the unit circle)
sec (theta) = 1 / (-3/5) = - 5/3
cot (theta) = 1 / tan(theta) = x-coordinate / y - coordinate
cot (theta) = -3/5 / y
y^2 + (-3/5)^2 = 1 => y^2 = 1 - 9/25 = 16/25 = y = +/- 4/5
Third quadrant => y = -4/5
=> cot (theta) = (-3/5) / (-4/5) = 3/4 
        
             
        
        
        
Answer:
80 is the measure because if aob is 40 then doe is 40 and  dof  is 120 minus the doe that  40 then you are going to get the mesuare which is 80
