Question

In triangle ABC , angle B = 90° , AB=BC, angleC= ?​

Answer 1

Step-by-step explanation:

in triangle ABC

GIVEN,

Angle B =90°

AB=BC

angle C =?

solut

Let angle A is x and angle C is 2x

(the sum of angles of triangle is 180)

angle A+ angle B +angle C = 180°

x+ 90 +x =180

2x = 180-90

x= 2/90

x=45

angle A is 45°

angle B is 90

and

angle C is 45°

Answer 2

Answer:

step by step explanation:

AB=BC

Angle C = angle A

Let say angle C = x

Angle A + Angle B + Angle C = 180° ( sum of angles of triangle)

=> x + 90° + x = 180°

=> 2x = 90°

x = 90°/2

x= 45°

angle C = 45°

Angle C = 45° if in a triangle ABC, Angle B=90° and AB=BC
