Answer 1

et Spice AE = DB = 3050 DE - BA - 2017 DC = BC = 10B = 4*30 H = 15 st. and ADB = X tan – Perpendiculars - Base DB - 30 > tand= 2 / 2 → a= tan (?) = 33.699 (Answer) ADB is hight angled triangle :: AD" = 408%+BAP AD = 108°+BA = 30° +202 - 11300 - 36.05 H. For triangle ABC which is right angled then A AC = CB + BA? * AC = 1e8f + BA? - Vigy+202 = 25 ft A length of sides of the triangle are A1 36.05 ft , De=15 H, AC=25 tt (Answer
