Answer:
There are 1.25 days in 30 hours or 1 1/4 days in 30 hours
Step-by-step explanation:
As we know one day is 24 hours. So if we divide 30 hours by 24 hours (or one whole day) then we get 1.25 days or also known as 1 1/4 days
 
        
             
        
        
        
Answer:
The height of the tree is H = 77.06 m 
Step-by-step explanation:
From Δ ABC 
AB = height of the tree

 
 
h = 0.9623 x ------- (1)
From Δ ABD

h = 0.77 (x + 20) ----- (2)
Equating Equation  1 & 2 we get
0.9623 x =  0.77 (x + 20)
0.9623 x = 0.77 x + 15.4
x (0.1923) = 15.4
x = 80.08 m
Thus the height of the tree is given by
H = 0.9623 x
H = 0.9623 × 80.08
H = 77.06 m
Therefore the height of the tree is H = 77.06 m
