Question

∆ abc=∆xyz and la=30°,lb=70° then Z equals​

Answer 1

Answer:

∠Z=80°

Step-by-step explanation:

Since you said that both the triangles are equal hence all angles are equal.. Respectively..

i.e ∠A = ∠X

    ∠B = ∠Y

    ∠C = ∠Z

Now in ΔABC

∠A+∠B+∠C= 180° [Angle Sum Property]

⇒ 30° + 70° + ∠C = 180°

⇒ ∠C = 180° - 100°

⇒ ∠C = 80°

∴ ∠C = 80°

Now as ∠C = ∠Z

∴ ∠Z = 80°
