B. parallelogram , rhombus , and rectangle
        
                    
             
        
        
        
The answer is 176 because 86+86=176
        
             
        
        
        
Answer:
θ = -33.69° 
Step-by-step explanation:
For Φ>0 and Φ<0  (in general Φ≠nπ  where n is an integer), sin(Φ) ≠ 0
Dividing both equations:

Therefore:
arctan(θ) = -2/3
   θ = -33.69° 
The answer does not depend on the sign of Φ, in fact we just need that the sine does not become zero, which occurs when Φ is equal to an integer times π (radians) or 180 (degrees)
Have a nice day!
