WebBy simple transformation of the cubic through an invertible substitution, the polynomial equation with the desired roots is: $\displaystyle \large c^3 + 4c^2 - 4c - 8 = 0$ Hence, by Vieta's Formulae for Sums and Products of roots, the value of the desired sum is $\displaystyle \large -4$ Share Cite answered Apr 24, 2024 at 13:31 Jack Tiger Lam Web31 mei 2024 · (ii) sec 4θ = cosec (θ – 20°), where 4θ and θ – 20° are acute angles. Answer: (i) θ and (θ + 36°) are acute angles sin (θ + 36°) = cos θ = sin (90° – θ) {sin (90° – θ) = cos θ} Comparing, we get θ + 36° = 90° – θ θ + θ = 90° – 36° 2θ = 54° ⇒ θ = = 27° ∴ θ = 27° (ii) θ and (θ – 20°) are acute angles sec 4θ = cosec (θ – 20°) jcpenney penney towel
