Answer:
180° is the correct answer. Hope this helped :)
Step-by-step explanation:
180°
a convex polygon has n sides, then its interior angle sum is
S = ( n −2) × 180°
S=(3-2)*180°=180°
the two numbers are 8 and 8
110÷360×π×4.6^(2)= 20.312
Area of sector = angle / 360 x π x r^(2)
It's for <em>n</em> = 1, 2, 3, …
for <em>n</em> = 1, 2, 3, …
