Answer:

f=43

Step-by-step explanation:

Hey There!

So if you didn't know the exterior angle (aka f) is equal to the sum of the opposite interior angles

so essentially what i am saying is that

19+24=f

19+24=43

therefore

f=43

hope this helps :)

if you have anymore questions just let me know
The sum of angles inside the Troy should be 180
19+24= 43
180-43=137
180-137=43
F=43
