Question

Please tell the answer​

Answer 1

Answer:

∠Y =55° ( vertex Y is congruent to vertex C hence ∠Y =55 degrees)

Step-by-step explanation:

given that Δ ABC ≅ Δ XYZ are congruent triangles.

then vertices AB=XZ , BC = YZ , AC = XY

        Angles ∠A = ∠X = 65°  

                     ∠B = ∠Z =  60°    

               similarly  ∠C = ∠Y =55°.

Answer 2

AS BOTH TRIANGLES ARE CONGRUENT,

SO, ANGLE C = ANGLE Y

ANGLE Y = 55°

ANOTHER METHOD:

TRIANGLE = 180°

SO IN TRIANGLE XYZ,

180° = 65° + 60° + Y

Y = 180° - ( 60° + 65° )

Y = 180° - 125°

Y = 55°
