Answer:
88.02 ft/s
Step-by-step explanation:
Angle with the horizontal, θ =25°
Initial velocity, v = 60 mph
1 mph = 1.467 ft/s
60 mph = 60 × 1.467 ft/s = 88.02 ft/s
Vertical component, v sin θ = 88.02 sin 25° = 37.2 ft/s
Horizontal component, v cos θ = 88.02 cos 25°= 79.8 ft/s
 
        
             
        
        
        
-10 -10y = 10
+10 +10
-10y = 20
20/-10 = -2
Y = -2
        
                    
             
        
        
        
Answer : 110 degree
To find angle 1 , we apply outside angle theorem  Lets name each point  Measurement of arc EF=280 degrees  
Measurement of arc GH = 60
Angle D = angle 1
Please refer to the theorem attached below  

Now we plug in the values

angle 1 = 110
Measurement of angle 1 = 110 degrees
 
        
             
        
        
        
So basically to estimate your answer, you must
        
             
        
        
        
6x/5 + 7 + -2x/3
