Answer:
x = 18
Step-by-step explanation:
All triangle angles add up to 180 so:
x + 5x + 72 = 180
6x + 72 = 180
6x = 180 - 72
6x = 108
x = 18
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
A <u>helix</u> is a curve for which the tangent makes a constant angle with a fixed line. The shortest path between two points on a cylinder (one not directly above the other) is a fractional turn of a helix, as can be seen by cutting the cylinder along one of its sides, flattening it out, and noting that a straight line connecting the points becomes helical upon re-wrapping (see attached diagram for helix).
The parametrization for the helix is

where  is the radius of the helix,
 is the radius of the helix,  is the constant, and
 is the constant, and  is the parameter
 is the parameter
 
        
             
        
        
        
Volume of cone = pi* r^2 *h/3
If you double the height ;
New volume = pi * r^2 * 2h/3
So, new volume will be twice as much.
        
             
        
        
        
<em>Answer:</em>
<em>In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.</em>
