Question

in∆ABC ,AB perpendicular BC, AB=BC then m angle A=?​

Answer 1

Step-by-step explanation:

Hope so that it will be useful

Answer 2

Answer:

In∆ABC

AB is perpendicular BC

so angle B=90⁰

and two sides are equal

AB=BC,so it is issoceles∆

so two angles are also equal

sum of all angle of∆=180⁰

So Angle A=angle C=x

x+x+angle B=180⁰

2x+90⁰=180⁰

2x=180-90

2x=90

x=90/2

x=45⁰

so Angle A=45⁰
