Daniel is constructing a fence that consists of parallel sides ab and ef. complete the proof to explain how he can show that the measure of angle gkb = 120° by filling in the missing justifications.

option a: 1. alternate interior angles theorem; 2. definition of congruence

option b: 1. alternate exterior angles theorem; 2. substitution property

option c: 1. definition of congruence; 2. alternate interior angles theorem

option d: 1. substitution property; 2. alternate exterior angles theorem

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
