I need some help plz

1. 1080°

2. (28) x (180) = 5,040 degrees

3. 120 degrees

4. Ff a regular polygon’s interior angles each measure 150 degrees, the exterior angles each measure 30 degrees, and therefore the regular polygon has 12 sides.

5. I think 10 yields 1... 1 is the number of sides the polygon has...

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
