Answer: z=35°
Explanation: First find X. All angles of a triangle adds up to 180°. To find x, add up all sides and set it equal to 180. 22+104+x=180. Solve for x. x = 54
A straight Line is 180°. Use x to find y. x+y = 180. Substitute x. 54+y=180 y = 126
To find z, find y + 19 +z = 180. Substitute y. 126+19+z=180. Solve for z. z = 35
