Question

In the given figure ab=bc what is the value of x. a=55​

Answer 1

Step-by-step explanation:

We have,

AB=BC

angle BAC = angle BCA = 55°

( OPPOSITE ANGLES OF EQUAL SIDES ARE EQUAL )

USING ANGLE SUM PROPERTY OF ∆ IN ∆ ABC , WE GET

angle ABC + angle BAC + angle BCA = 180°

x+55°+55° = 180°

x=180°-110°

x=70°

Thus , x=70°
