HELP PLEASE! I don't understand this problem.

So, you have to prove that Triangle ABC is congruent to Triangle ADC

&

it has been proved that they are congruent.

Step-by-step explanation:

We already know that Angle B is congruent to Angle D and AC bisects Angle BAD.

Because given rules one angle of one triangle is equal to the same side of the other.

Because of bisection, you also now know that Angle BAC is congruent to Angle CAD.

The sum of a triangle is 180 degrees.

Angle B and Angle BAC are equal to Angle D and Angle CAD.

180 degrees subtract from both of these if you knew the degrees would give the same answer.

This proves they are congruent.

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
