Question

An equilateral triangle ABC is inscribed in a circle with center o. What will be the measure of /boc​

Answer 1

120 ° ...................
in equilatral △
all sides are 60 °
so one ∠ will half of ark
∠ ABC = 1/2 m(arc AB)
so ∠ ABC×2=m arcAB opposite to it and so the arc will 120 °
box is central ∠
arc opposite will same as arc and so the ∠ will also the same
.......central ∠ theorem

Answer 2

Answer:

Step-by-step explanation:

angle subtended by an arc at the centre is  double the angle subtended by it on any other part

<boc= 2 * 60 = 120
