Question

In the given figure, find ∠ B.

Answer 1

Answer:

ANGLE B WILL BE 60 AS ANGLE A WILL BE 70..ANGLE C 50(OPPOSITE ANGLES)

Answer 2

Answer:

60°

Step-by-step explanation:

angle ECD = angle BCA ( by vertically opposite angle property)

therefore , angle BCA = 50°

angle FAC + angle CAB = 180° ( angles on straight line )

therefore, angle CAB = 180° - 110° = 70°

now,

angle ABC + angle BCA + angle CAB = 180°

( summation of all angles of a triangle)

so,

angle ABC + 50° + 70° = 180°

angle ABC= 180° - 120° = 60°
