The sum of the interior angles of a polygon with N sides is (N-2) x 180 degrees.
For a 30-gon, the sum of interior angles is (28) x (180) = 5,040 degrees .
It makes no difference whether or not the polygon is convex at every vertex.
There's an equation for that:
Sum of interior angles = 180(n - 2) where n = number of sides
So if you have a polygon with 30 sides, the sum of the interior angles is:
180(30 - 2) = 180(28) = 5040 deg
The sum of the measures of the interior angles of a convex 30-gon is 5040 degrees, calculated using the formula ( N − 2 ) × 18 0 ∘ . This holds true regardless of whether the polygon is convex or concave. The calculation highlights the consistent relationship between the number of sides and the angles in polygons.

Jawaban:Satu ton hotmix dengan ketebalan 4 cm akan menutupi area sekitar 8.7 m².Perhitungan ini didasarkan pada asumsi berat jenis aspal hotmix rata-rata 2.3 ton/m³, dan rumus konversi: Luas (m²) = (1 ton / densitas) / ketebalan. Penjelasan dengan langkah-langkah:Penjelasan:Rumus: Luas (m²) = (1 ton / densitas) / ketebalanDensitas (Berat Jenis) Aspal: Rata-rata 2.3 ton/m³ (bisa berbeda tergantung jenis hotmix).Ketebalan: 4 cm = 0.04 meter. Perhitungan:Luas = (1 ton / 2.3 ton/m³) / 0.04 mLuas = 0.4348 m² / 0.04 mLuas ≈ 8.7 m²
