Answer:
(N+n)=(A+a)
Step-by-step explanation:
Let N represent Nick's current weight
Let A represent Adam's current weight
Let n represent weight Nick gains weekly
Let a represent weight Adam looses weekly
100-20 round the last numbers so they have a 0 at the end so 4 or under is 0 and 5 or higher is 10 so 100 - 20 is 80
Graph the absolute value by using the vertex and a few selected points
Point One: X= -1, Y= -8
Point Two: X= 0, Y= -2
Point Three: X= 1, Y= 4
Point Four: X= 2, Y= -2
Point Five: X= 3, Y= -8
The graph should look something like a mountain or an upside down V
If two angles are known to be the same, the triangles are similar! If this is true, then by default the third angle will be the same. So, triangles that have two of the same angles MUST be similar!
