Question

In the given figure, AB || DC and BCE is a straight line.
If angle ABC = 50° and angle BAC: angle ACB = 2:3, find angle ACD.​

Answer 1

Answer:

angle abc =50 given

ab// dc means angle abc = angle dce =50

straight line angle sum = 180 degrees

here straight line= angle ABC +ACD+DCE

180=50+angle ACD+50

180=100+ACD ANGLE

ANGLE ACD =180-100=80

Angle ACD=180
