Question

please answer this question. its my hw so please tell with explanation i know there answer​

Answer 1

Answer:

180°

Hope it helps u !!!!

Answer 2

Answer:

answer is 200 degrees

Step-by-step explanation:

firstly in triangle AOB ,

AO will be equal to BO becz both r radii of circle hence angle ABO is equal to angle OAB =60 degree because the angles opposite to equal sides are also equal so angle OAB =60

Now similarly AO =OC hence angle OAC=angle OCA =40

then angle BAC=angle OAB+angle OAC=60+40

=100

and we know that angle BAC =1/2BOC

so angle BOC =2×BAC=2×100=200 degrees

that will be the answer .hope it will be helpful for u
