Geometry - finding value of x. need fast, will give 5 stars + !

x=16

Step-by-step explanation:

We are given a ΔAGL.

E and N are the points on line AL and AG respectively.

Refer the figure

We can see that EN = 21 and LG = 42

⇒ EN is half of LG and we can see that EN is parallel to LG

So, mid segment theorem states that the segment passing through the  midpoints of two sides of triangle and parallel to third side then it is also half of the third side.

So, Since EN is half of LG and we can see that EN is parallel to LG

So, E is the mid point of AL i.e. AE =AL and N is the midpoint of AG i.e.

AN = NG

Now since AN = NG

And we can see that AN =2x-9

And NG = x+7

⇒2x-9 = x+7

⇒2x-x = 7+9

⇒x = 16

Thus the value of x is 16

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
