Answer:
x = 46
Step-by-step explanation:
Since the angles are equal to each other, make the equations equal to each other.
4x - 36 = 3x + 10 and simplify
x - 36 = 10
x = 46

If an adult blinks 450 times in 30 minutes, then he will blink 900 times in 60 minutes.
A 12-year old blinks 150 times in 15 minutes, so he will blink (150 x 4) in 60 minutes, which comes out to: 600. 
so 900-600
An adult blinks 300 times more in 60 minutes than a 12-year old. 
 
        
             
        
        
        
0=-16t^2 +64
0=-16(t^2 - 4)
0=-16(t-2)(t+2)
t=2 or - 2
It will take two seconds for the object to hit the ground.
