In what cases are we allowed to assume an angle measure? In what cases are we allowed to assume a segment length?

If we are given the expressions for multiple angles or line segments, what should we look for in order to make equations with these expressions?

The function g(x) is defined as shown. x-1, -2 g(x) = 2x+3, -1 6-x, x23
