Answer:

110 degrees

Step-by-step explanation:

We know that all of the angles in a triangle add up to 180 degrees, so we can add up all of the angles and set it equal to 180 degrees.

f= angle f

30+40+f=180

70+f=180

f=110
30 + 40 + f = 180
You take what you know ( 30 + 40 ) and then subtract that sum ( 70 ) from the total ( 180 ) and you get a remainder of 110 which will be your f value. F= 110
