Q. 13X is a point inside triangle PQR. It is 3cm from P, and 4cm from Q. How far is X from R ?
Identify Problem: Identify the problem as finding the distance from point X to vertex R in triangle PQR, where distances from P to X and Q to X are known.
Use Triangle Inequality Theorem: Use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Apply Theorem: Apply the theorem: Let's denote the unknown distance from X to R as d. According to the triangle inequality:1. PX+XR>PR2. QX+XR>QR3. PX+QX>PQGiven PX=3cm and QX=4cm, we can write:1. 3+d>PR2. 4+d>QR3. 3+4>PQ
Additional Information Needed: Since we don't have the values for PR, QR, or PQ, we cannot directly calculate d using these inequalities. We need additional information about the triangle or a different approach to solve for d.
