Answer:
x = 129º
Step-by-step explanation:
It will take some time to elaborate but start this way:
you see the triangle with the 58º and 57º? Now by rule, the sum of all angles ina triangle is 180º 
so 57+58 =  115
to discover the other angle you just have to 180-155 = 65
Now that you know the 65º by rule the angle facing it is exactly the same, follow from there, solve all triangles until you get to x...
 
        
             
        
        
        
Answer:
d=10.0002
Step-by-step explanation:
Given That:
Height=h=28 inches
Volume=V=732.7 cubic inches
Required:
Diameter of the base of the cone=d=?
Solution:
the formula for the volume of a cone is
re-arranging the terms to get the radius (r)
putting values, we get
to find the diameter we know that diameter is double of the radius so
d=2r
d-2(2.0051)
d=10.0002
 
        
             
        
        
        
The approximate value of x in the square that the diagonals meets to form four right angles is 5.7 units
<h3>Properties of a square.</h3>
- All the sides are equal.
- Opposite sides are parallel to each other.
- The diagonal intersects at right angle.
Using Pythagoras theorem the value of x can be found as follows:
c² = a² + b²
where
- c = hypotenuse 
- a and b are other legs
Therefore,
8² = x² + x²
64 = 2x²
x² = 64 / 2
x = √32
x = 5.65685424949
x = 5.7 units
