Answer:
48 m
Explanation:
arctan(28) = TreeHeightSeenFromHisEyes/30
TreeHeightSeenFromHisEyes = 30 * arctan(28)
TreeHeightSeenFromHisEyes = 30 * 1.53509721411557
TreeHeightSeenFromHisEyes = 46.0529164234672
Do not forget to add 2 meters because that is approximately where the eyes of the man are located in respect to the ground on which the man is standing.
46.05 + 2m = 48,05m
Please note you need to answer for nearest WHOLE number, so the answer is 48 m
