Question

in triangle abc of ab =ac and angle c=54degree then angle b is​

Answer 1

Answer:

72

Step-by-step explanation:

As two sides of triangle are equal then it is a isosceles triangle... so In an isosceles triangle opposite side and opposite angles are equal so.. 108+ <a = 180 so angle A = 72

Answer 2

Step-by-step explanation:

angle B = angle C = 54°

let angle A be x.

In ∆ABC

angle A + angle B+ angle C = 180

=> X + 54 + 54 = 180

=> X + 108 = 180

=> X = 180 - 108

=> X = 72

angle A = 72°

angle B = 54°
