Answer:
z = 35
Explanation:
Use the triangle angle sum theorem which states that the interior angles of a triangle sum to 180 degrees. The angles it refers to are the angle measures at each vertex. (Each point of the triangle)
You do not need x and y for this question. They are not angle measures at the vertex.
22+19+104+ z = 180. Combine like terms.
145+z= 180. Subtract 145 from both sides.
z= 35
