The word-final sequence <gue> is simply ɡ in many words. Here are quite a lot of them:
brogue catalogue colleague demagogue dialogue epilogue fatigue fugue Hague intrigue league monologue morgue pedagogue plague Prague prologue rogue synagogue travelogue vague vogue
The word-final sequence <ngue> is pronounced ŋ. Examples:
harangue meringue tongue

ague = ˈeɪɡjuː
argue = ˈɑːɡjuː
dengue = ˈdeŋɡi
Montague = ˈmɒntəɡjuː
segue = ˈseɡweɪ
