The third term would be 5h2 because the descending order would be
-2h4 - 8h3 + 5h2 - 2h - 3
Right angle is the answer I think ( not sure though )
The ratio is width over length.
Make a fraction with the width on top and the length on the bottom:
44/70
Both numbers are even and can be divided by 2,
so the simplified fraction becomes 22/35
