A(t)=A0*(1/2)^(t/30)
where t=elapsed years
A0=initial mass at t=0.
        
             
        
        
        
Answer:
V=14
Step-by-step explanation:
Well its a supplementary angle if you add everything together. 
We know theres a 90 degrees angle and a 34 degree angle. 
90+34=124
124+4v=180 
Since if you add everything up its a straight line 
Solve the equation normally 
56=4v
14=v
