The room is not in shape of a square but a rectangle.
Question says Length is: 19 inches 
Diagonal is: 20.6 inches
In a square all sides are equal
Rectangle has just two sides equal
 
        
             
        
        
        
Answer:
Y= 20 
X= 25
Step-by-step explanation:
The angles of a triangle have to equal 180
So 
 80+60 = 140
180 - 140 = 40 
40/2 = 20 
Y = 20 
The angles of a linear line split equal 180 
So 
2y is one side of it which we learned Y = 20 which makes that side 40 
To find the other side just guess and check 
6(25) = 150 
150 - 10 = 140
So the 2y = 40 and the (6x-10) = 140 
So yea boom done
 
        
             
        
        
        
Answer:
y = 5x + 3
x = 5y + 3
5y + 3 = x
5y = x - 3
y = x/5 - 3/5
f^-1(x) = x/5 - 3/5

Answer:
Do you mean g as in the acceleration due to gravity on Earth?
if so, it is 30.5g= 30.5 x 9.81 = 299.205 m/s^2
