Answer:
15
Step-by-step explanation:
Let the left side of the triangle be 2Y for the bigger triangle and then the smaller one will be Y.
Comparing the two triangle
2Y/Y = 30/X
2 = 30/X
Cross multiple
2X = 30
Dividing by 2
X = 30/2
X = 15
Three noncollinear points are contained in one and only one plane -- flat plane postulate. If two points are in a plane, then the line containing the points is in the same plane -- plane intersection postulate.
For graphs, always start with line <em>x</em> then do line <em>y</em>.
Answer:
The final set of ordered pairs represents a function.
Step-by-step explanation:
Each X value corresponds to exactly one y- value. Essentially, none of the x values are the same in the final set.
You have to multiple and divide
