Answer 3

what you need help with

Answer 4

"penta-" means "5" in this context.
What is the sum of the interior angles of a 5-sided geometric figure?

Answer 5

90?

Answer 6

The sum of the interior angles depends upon how many sides there are. I suggest you look up on the 'net "sum of interior angles." Bet you'll immediately find the formula you need.

Answer 7

No. The sum of the interior angles of a triangle (3 sides) is 180 deg.
That of a 4-sided figure would be greater,
and that of a 5-sided figure would be greater still. Again, look up "sum of interior angles."

Answer 8

360
