Answer:

Step-by-step explanation:
Slope of straight line can be calculated as

Here 

Equation of straight line in slope intercept form is


 
        
             
        
        
        
3(9) = 27 
3(7) = 21 
3(9+7) = 48 
27+21 = 48 
48=48
        
                    
             
        
        
        
3/4
3.0/4=0.7R0.2 or 0.7 + 0.2/4
0.20/4=0.05R0.00 or 0.05 + 0.00/4
now put it all together
0.7R2 = 0.7 + 0.05R0.00 = 0.75 + 0.00 = 0.75
        
             
        
        
        
If B is the midpoint of ZA, then ZB = <span>BA
</span>3x-5 = <span>x+3
3x - x = 3 + 5
2x = 8
x = 8/2
x = 4
</span>ZA = ZB + BA
      =  3x-5 + x+3
      = 3*4 - 5 + 4 + 3
      = 12 - 5 + 7 
      = 14

Answer: <em>∠1 = 37.5°; ∠2 = 37.5°; ∠3 = 133°.</em>
Step-by-step explanation:
<em>∠1 = ∠2 = (180° - 105°) ÷ 2 = 37.5°</em>
<em>∠3 = 180° - 23° - 24° = 133°</em>
