Web12 mrt. 2024 · ∠Y = 40° Step-by-step explanation: Given, In ΔABC, AB = 3 cm BC = 6 cm, AC = 2 cm ∠A = 80° ∠B = 60° In ΔXYZ, XY = 4√3 cm, YZ = 12 cm XZ = 6 cm Since, AB/XZ = AC/ XY = BC/YZ 3/6 = 2 cm/4√3 cm = 6/12 1/2 = 1/2 = 1/2 Thus, ΔABC ≈ ΔXYZ with SSS congruency. Now, In ΔABC; ∠A + ∠B+ ∠C = 180° 80° + 60° + ∠C = 180° ∵ ∠C = 40° WebAD ⊥ BC at D AB = 12 cm AC = 16 cm Concept used: Pythagoras' theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides. Calculation: AB 2 + AC 2 = BC 2 ⇒ 12 2 + 16 2 = BC 2 ⇒ 144 + 256 = BC 2 ⇒ 400 = BC 2 ⇒ 20 = BC Now, using similarity of triangle ABC and DBA.
