Answer: 2340
Explanation:
Use the formula below with n = 15
S = 180*(n-2)
S = 180*(15-2) ... replace n with 15
S = 180*13
S = 2340
This formula is based on the idea that a triangle's interior angles add up to 180, and the idea you can partition any polygon into triangles (aka "polygon triangulation")
Answer: 720°
Step-by-step explanation:
Use the formula for the Sum of interior angles: I = 180(n - 2) , where n is the number of sides/angles.
I = 180(15 - 2)
= 180(13)
= 720
