130 degrees is the total degrees of the angle, So if part of that angle was 70 degrees with a missing part you can just subtract to find the missing angle. (130-70=60) The missing angle equals 60 degrees
i think its 60 because 130-70 = 60
The measure of the other part of angle F is 60 degrees, calculated by subtracting the known part of 70 degrees from the total of 130 degrees.
