In the diagram below, \text{m}\angle A = 58^{\circ},m∠A=58 ∘ , \text{m}\angle B = 55^{\circ}m∠B=55 ∘ and \text{m}\angle C = 79^{\circ}.m∠C=79 ∘ . Find \text{m}\angle D. m∠D.

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = initial mass (at time t = 0) n = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
