Answer:
x = 77 degrees
Step-by-step explanation:
All angles of a trapezoid will add up to equal 360 degrees.
In other words: 60 + 128 + 95 + x = trapezoid
60 + 128 + 95 = 283 degrees.
360 - 283 = 77
x = 77 degrees
Check your work:
60 + 128 + 95 + 77 = 360
188 + 95 + 77 = 360
283 + 77 = 360
360 = 360
Correct
