Mathematics Questions

A triangle has a side length of 26 in. A line parallel to this side divides the triangle into two equal area parts. What is the length of the segment cut off by the other two sides of the triangle?

Short Answer

To determine the length of the segment cut from a line by two sides of a triangle with a side length of 26 inches, we calculate using the formula d = sqrt((L/2)² + (L/2)²). After simplification, the length of the segment is found to be 13√2 inches.

Step-by-Step Solution

Step 1: Understand the Problem

We need to determine the length of a segment cut from a line by two sides of a triangle. The side length of the triangle is provided as L = 26 inches. Knowing this, we will calculate the length of the segment using geometric principles.

Step 2: Calculate the Length of the Dividing Line

To find the length (d) of the line that divides the segment, we use the formula: d = sqrt((L/2)² + (L/2)²). This requires us to first calculate (L/2):

  • Calculate L/2: 26/2 = 13
  • Substitute into the formula: d = sqrt(13¬≤ + 13¬≤)

Step 3: Simplify Your Result

Now we simplify the expression for d. Rewrite it as d = sqrt(13² * 2), which leads us to:

  • Taking the square root gives: d = 13‚àö2
  • This shows that the length of the segment cut from the line is 13‚àö2.
