Answer: 105
Explanation:
This is an interesting question. I would rewrite it as
In triangle FGH, angle FGH=25° and angle FHG=50. What is the measure of ∠HFG?
In the original question, the answer could technically be 25 or 50 is angle HFG.
Assuming that HFG is not equal to 25 or 50, the answer is 180-25-50, or 105. (the sum of the inner angles of a triangle is 180)
