Diagonal of pentagon formula

WebWe can find the number of diagonals of the given polygon with the formula, Number of diagonals = n(n-3)/2. Substituting the value of n = 15. n(n-3)/2 = 15(15-3)/2 = (15 × 12)/2 = 90. Therefore, the polygon has 90 diagonals. Ques 2. Determine the diagonal of a rhombus whose area is 50cm2 and one of its diagonal measures is 7cm. WebOct 29, 2012 · sin α + sin 2 α + sin 3 α + ⋯ + sin ( n − 1) α, where α = π n. There is a pleasantly simple formula for this kind of sum: see here. This formula is most easily proved by using complex numbers, for then we are just dealing with the sum of two geometric progressions. In that formula, let φ = 0, and use n − 1 instead of n.
