Answer 2

D on first one

Answer 3

I'm narrowing the second one down to either a or c, and when any two sides of a triangle are added, the remaining side cannot be bigger than the sum of those two sides, or smaller than the two sides subtracted

Answer 4

(n-2) * 180 so A on the second one

Answer 5

Thank you so much!

Answer 6

Just to clarify why, D is the answer to the first question because the two smaller lengths of the triangle must be greater than the biggest length
