answer of this question

Answer 1

given here that
angle A A is equals to 75 degrees
if angle A equal to 75 degree then angle ACE is also 75 degree because of alternate interior angle
therefore angle ACB is equals to 180 - 75 + 40 that is 180 - 115 which is equals to 65 degrees because of linear pair
So, using angle sum property of a triangle angle abc equals to 180 - 65 + 75 that is 40 degree
therefore the final answers are as follows:
angle ACB equals to 65 degree and Angle ABC equals to 40 degree
