Answer 2

Answer:

hey here is ur answer.....................

Step-by-step explanation:

<ebc=102 degree.

<abc=180degree -102 degree

       =78 degree

<acd=128 degree

<acb=180 degree-128 degree

       =52 degree.

THIS IS BECAUSE THEY ARE LINEAR PAIR.

LINEAR PAIRS ARE SUPPLEMENTARY that is 180 degree.

<abc+<bac+<acb=180 degree

THIS IS BECAUSE OF ANGLE SUM PROPERTY OF A TRIANGLE.

SO,78 degree+53 degree+<bac=180 degree

131 degree+<bac=180 degree

<bac=180 degree -131 degree

<bac=49 degree..
