Answer:
90
Step-by-step explanation:
Angle 2 = 180 - 68 = 112
Angle 3 = 90 - 68 = 22
Angle 2 - Angle 3 = 112 - 22 = 90
 
        
             
        
        
        
4(2x5 + 3) - 4(2) + 2(5).
4(13) - 18.
52-18 = 34.
        
                    
             
        
        
        
Answer:
Any number greater than 43.54 and less than 43.6 rounds to 43.6. So, 43.55, 43.56, 43.57, 43.58 and 43.59 all round up to 43.6.
 
        
             
        
        
        
Answer: 50 km
Step-by-step explanation: So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by  
2.5
/1
. Then, 20 x 2.5=50. So the answer is 50 km
