Cartesian Grid - Area (Obtuse Triangle) to Missing Coordinate - Positive Only (Level 1)

This math topic focuses on finding missing coordinates on a Cartesian grid for obtuse triangles, using the given triangle area (in positive coordinates only). It requires understanding the relationship between the area of a triangle and its vertex coordinates, and applying geometric and algebraic principles to solve problems. Each question requires determining either the missing x or y coordinate with multiple-choice answers provided. This is part of broader practice on Cartesian Grid Geometry Logic.
