Answer:

hey here is your answer

pls mark it as brainliest

Step-by-step explanation:

so here we just need to apply angle sum property on triangle abc

so thus we get

angle abc+angle bac+angle acb=180

substitute given data in it

we get

angle bac=180-(69+31)

=180-100

=80 degrees

hence angle bac=80 degrees
