Question

In the given figure, if angle DAB=60°, angle ABD=60°, then angle ACB is equal to​

Answer 1

Answer:

60

Step-by-step explanation:

angle DAB+angle DBA+angle ADB=180°(angle sum)

angle ADB=180-120=60°

Angle ACB=60°(angles subtendedon the same segment is equal)

Answer 2

Answer:

Angle ADB = angle ACB ( angles subtended by same segment are equal )

Angle ADB = 180-(60+60)

= 60

Therefore angle ACB = 60
