Identify the values of variables x, y, and z based on the image given of the angles formed by a transversal and parallel lines

Step-by-step explanation:

Let's start by identifying relevant angle theorems for two parallel lines cut by a transversal.

Alternate Interior Angles Theorem

Two angles that are on different sides of the transversal and inside of the two parallel lines are congruent (=).

Alternate Exterior Angles Theorem

Two angles that are on different sides of the transversal and outside of the two parallel lines are congruent (=).

Same-side Interior Angles Theorem

Two angles that are on the same side of the transversal and inside of the two parallel lines are supplementary (= 180).

Same-side Exterior Angles Theorem

Two angles that are on the same side of the transversal and outside of the two parallel lines are supplementary (=180).

Corresponding Angles Theorem

Two angles on a figure that correspond are congruent (=).

Now, let's look at the figure and apply these theorems.

and are same-side exterior angles, meaning they're supplementary:

Subtract from both sides of the equation:

Now that we know our value, let's recognize that ()corresponds to , meaning they're congruent:

Subtract from both sides of the equation:

Let's find the value of the angle:

Add:

Since the corresponding angles are of the same value, they're congruent, proving our & values correct.

_

Since and the angle represented by the expression (°) are alternate-interior angles, they are congruent:
