#SPJ1
Answer:
3240°
Step-by-step explanation:
For a regular icosagon,
sum of interior angles measure=180(n-2)°
180(20-2)
180(18)=3240°
The angle measure is 78/2 degrees. that would simplify down to 39 degrees. I don't remember the theroem but I do know that the angle is half the side length angle measure
