The answer is 120. Because inscribed angle is Half of the arc measure. Double 60 and we get 120.
        
                    
             
        
        
        
In real-life physics, acceleration due to gravity will change respect to altitude. Check out the attached image (source: Wikipedia).
However, in high-school physics, acceleration due to gravity is represented by the letter g, which has a value of 9.81 meters per second squared.
This means that an object being dropped straight down will be moving 9.81 meters per second faster than it was 1 second ago. I hope this helps! :)
 
        
        
        
i don’t know but you could prob use photo math. that would hell
        
                    
             
        
        
        
C: is the speed of light (3*10^8 m/s) and it is squared (raised to the power 2) in this equation.
