Question

In the given figure, m AD= 79° and m∠AEB = 83°. What is the measure of arc BC?

Answer 1

Answer:

hey here is your answer

pls mark it as brainliest

so here we go

Step-by-step explanation:

now here as angle aeb is a central angle

it would intercept equal arcs on its opposite side

so hence m(arc ab)=m(arc dc)=83

so use arc addition property

you get m(arc bc)=360-(83+83+79)

=360-245

=115

hence m(arc bc)=115
