Answer:
   A ≈ 65.4°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the trig relations associated with pairs of sides. For angle A, given sides b and c are the adjacent side and the hypotenuse, respectively. The appropriate relation is ...
   Cos = Adjacent/Hypotenuse
   cos(A) = b/c
   A = arccos(b/c) = arccos(2.5/6)
   A ≈ 65.4°
 
        
             
        
        
        
To find the volume of something, you do the area times the height. In this case you already know the volume so you solve it like this:
(x represents the height since you don't know the value) 
1440= 144 * x
1440 = 144x 
1440/144= 144x/144
10 = x
Your height is 10:)
 
        
             
        
        
        
No. I would say 50/50 chance. This answer probably isnt helpful :/
