A polygon is convex means that given any two points on or inside the polygon, the segment joining the points lie entirely in the polygon. Use mathematical induction to prove that for every integer n ≥ 3, the interior angles of any n-sided convex polygon add up to 180(n − 2) degrees.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

first one because it can't have a fraction in it
