The value of x will be 6
<u><em>Explanation</em></u>
According to the below diagram, UW is the angle bisector of ∠TUV
<u>That means,</u> 
Given that,
and 
So, the equation will be......

So, the value of x will be 6.
Consider the equation

1) First row of the table
Set x=0 and solve as follows:

The answer is y=20 and the pair x-y is (0,20)
2) Second row
Set x=1 and solve, as follows:

The answers are y=10 and (1,10)
3) Third row.
Set y=0 and solve as follows:

The answers are x=2 and (2,0)
Answer:
Step-by-step explanation:
(7,6) (-3,-1)
(x1,y1) (x2,y2)

The shape has five edges (if your including the point at the top) and five faces
