Answer:

Step-by-step explanation:
The sum of the measures of the interior angles of each convex n-sided polygon is always equal to

1. A pentagon is 5-sided polygon, then the sum of the measures of the interior angles of pentagon is

2. An octagon is 8-sided polygon, then the sum of the measures of the interior angles of octagon is

3. A dodecagon is 12-sided polygon, then the sum of the measures of the interior angles of dodecagon is

4. For 40-sided polygon the sum of the measures of the interior angles is

5. For 52-sided polygon the sum of the measures of the interior angles is

6. For 100-sided polygon the sum of the measures of the interior angles is

the place i got this from tbh i don't understand what you want for an answer but i tried, so here is a website that i got these from i hope it helps you.
Step-by-step explanation:
Evaluate for a= 1/3
3(1/3)+4(1/3) = 7/3
Evaluate for a= 1.5
(3)(1.5)+(4)(1.5)
=10.5
Evaluate for a=
(3)(2)+(4)(2)
=14
