Answer:
131°
Step-by-step explanation:
(disclaimer this isn't necessarily right, please don't come at me if this is wrong)
So the only we have is the measurement of angle H, which is 49°. So we're going to assume that they're all equal, cause I don't know what else to do, so:
180° - 49° = 131°
So, I think that angle F is 131°
hope this is right and helps:)
