2 questions? medals
Which of the following are NOT the lengths of the sides of a triangle? A. 2,3,4 B. 2,3,2 C. 2,3,3 D. 2,3,6 Which one of the following formulas will find the sum of interior angles of a polygon with n sides? A. 180(n-2) B. 180(n-360) C. 180(n-1) D. 18n
D on first one
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
(n-2) * 180 so A on the second one
Thank you so much!
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

Thank you @master50777 for clarifying the first question.
