Final answer:
Without the exact problem, it is difficult to solve for x, y, and z. The given equation suggests an angle-related problem where x, y, and z could represent vector components or points in space.
Step-by-step explanation:
Based on the information provided, it appears that the question is related to solving for variables x, y, and z in given mathematical expressions or equations.
The prompt mentions an equation with a sum of 11° comprising two terms involving x, 2x+16° and 3x-5°, which seem to be related to angles. Without the exact problem, it is challenging to provide a precise solution.
However, solving such equations typically involves isolating the variable on one side and simplifying the terms. Additionally, the reference to a coordinate system suggests that these variables might represent vector components or refer to points in a three-dimensional space.
