Answer 1

Answer:

hey your answer is as follows

so pls mark it as brainliest

Step-by-step explanation:

so here use angle sum property of triangle in triangle abc

so we get

angle a+b+c=180

ie angle a+50+70=180

=180-120

=60

so since here ab/ac=bd/cd

we can say that ad is bisector of angle a by converse of angle bisector property

thus then angle bad=angle cad=1/2×angle a

ie angle bad=1/2×angle a

=1/2×60

=30 degrees

hence option a is ryt
