Ответ:
40 degrees
Step-by-step explanation:
The answer is 40 degrees. Angle x and angle y form vertical angles, therefore x = y. Angle y forms a straight line with the 80° angle and the 60° angle which means that 80° + 60° + y = 180°. 140° + y = 180°. y= 180° - 140°. y = 40°. As mentioned earlier: x = y, so x = y = 40°.
Hope this helps
