Question

if triangle ABC is congruent to triangle d e f and angle A equal to 50 degrees and angle F is equal to 60 degrees .then find Angle B

Answer 1

ABC ≈DEF
∠A=√D=50
Than √F=√C=60
So -A+B+C=180
=50+B+60=180
=B=180-110
B=70
                         √B=√E=70
I hope you understand

Answer 2

Hi.

Good Question...Keep Progressing...

Here is your answer---

Given---
              Δ ABC is congruent to ΔDEF
Thus,
 By CPCTC [Corresponding Parts of Congruent Triangles are Congruent].
      ∠ A = ∠ D = 50° 
      ∠ B = ∠ E 
      ∠ C = ∠ F = 60°
Now,

   Using the angle sum property,
    ∠A +∠B + ∠C = 180°
     50° + ∠B + 60°  = 180°
      110° + ∠ B = 180°
              ∠ B = 180° - 110°
              ∠ B = 70°

Thus, the value of the ∠B is 70°.
