Answer:
cos P = 53 degrees
cos Q = 37 degrees
Step-by-step explanation:
cos P = 
cos P = 
cos P = 0.60
Cos-1 of 0.60 is 53.13 (round to the nearest whole number)
cos P = 53 degrees
cos Q = 
cos Q = 
cos Q = 0.80
Cos of 0.80 is 36.86 (round to the nearest whole number)
cos Q = 37 degrees
To check anser: 
90 + 53 + 37 = 180
180 = 180
 
        
             
        
        
        
 
rise/run 1/4 so it can be 
 
        
                    
             
        
        
        
Answer:
The domain will be all real numbers, range will be all real numbers below -3
Step-by-step explanation:
its quadratic so it goes forever left and right. but the vertex has a y value of -3. It is a negative sloped graph, so anything below that is in the range
 
        
             
        
        
        
1/10 = .1, and 3/33 = .0909090... it is equivalent if you estimate.
