Answer:
D: 12
Step-by-step explanation:
The entire segment KI is composed of the segments KJ and JI. So: 

We know that KI is 15. 
KJ is (2x-15) and JI is (2x-6). Substitute: 

Solve for x. Combine like terms: 

Add 21 to both sides: 

Hence, the value of x is: 

We know that JI is 2x-6. 
We will substitute 9 for x to find JI. So: 

Hence, our answer is D. 
 
        
             
        
        
        
First it can be a 2,4,6,8. Four numbers. 
Then one is removed, leaving three numbers. 
Then one is removed, leaving two numbers. 
Possibilities for that to happen: 4*3*2 = 24. 
Total amount of possibilities: 9*8*7 = 504. 
So the answer is A: 24 out of 504.
        
                    
             
        
        
        
Answer:
B. Orthocenter
Step-by-step explanation:
The orthocenter of a triangle is the point of intersection of the three altitudes (the perpendicular from a vertex to the side facing the vertex) of a triangle
The steps used in constructing the orthocenter includes the steps for drawing of the perpendicular to the sides of the triangle from a point which is the vertex opposite the side of the triangle
Therefore, in the given diagram, a perpendicular to the side KS is drawn from the (vertex) point <em>W</em>, by drawing an arc with center at <em>W</em> that intersects the side KS at two points. Rom the points of intersection of the arc drawn from <em>W</em> intersects KS, with the compass, two arcs are drawn to intersect at a point from which a line drawn to <em>W</em>, is perpendicular to KS
Therefore;
The correct option is B. orthocenter
