Question

Find the centroid of a triangle bounded by the lines 4x−y+18=0,3x−13y−11=0, and 5x+11y−51=0.

Answer 1

To find the centroid of the triangle bounded by these lines, we first need to find the intersection points of the lines to determine the vertices of the triangle. Then we can use the coordinates of the vertices to calculate the centroid.

Step-by-step explanation:

First, let's find the intersection points:

1. Solve the first two equations to find the intersection point of the lines 4x−y+18=0 and 3x−13y−11=0.

2. Solve the second and third equations to find the intersection point of the lines 3x−13y−11=0 and 5x+11y−51=0.

3. Solve the third and first equations to find the intersection point of the lines 5x+11y−51=0 and 4x−y+18=0.

Once we have the intersection points, we can use the coordinates of the vertices to calculate the centroid using the formula:

Centroid = (x1 + x2 + x3)/3, (y1 + y2 + y3)/3

Where (x1, y1), (x2, y2), and (x3, y3) are the coordinates of the vertices of the triangle.

Answer 2

To find the centroid of a triangle bounded by the given lines, solve the system of equations formed by these lines to find the intersection points, which will be the vertices of the triangle. Then, find the intersection of the two intersection points with the third line to find the centroid.

Step-by-step explanation:

To find the centroid of a triangle bounded by the lines, we need to find the intersection of these lines. We can solve the system of equations formed by these lines to find the coordinates of the intersection point, which will be the centroid. Start by solving any two pairs of equations to find two intersection points. Then, find the intersection of one of those points with the third line to find the centroid.

Let's solve the equations:

1. Solve equations (1) and (2) to find the coordinates of the first intersection point.
2. Solve equations (1) and (3) to find the coordinates of the second intersection point.
3. Find the intersection of the two intersection points found in steps 1 and 2 with equation (2) to find the coordinates of the centroid.
