Answer:
67
Step-by-step explanation:
angles on a straight line add up to 180 degrees
so 180 - 127= 53 to get the angle on the bottom left.
60 + 53 = 113
angles in a triangle add up to 180 degrees so 180-113= 67
to double check you should add
60+53+67 if you get 180 then its correct!
hope it helps :)
