Question

In the circle below, if the measure of arc ACB = 260 °, find the measure of < B.

Answer 1

Given:

There is a figure given in the question as below

Required:

If

`arcACB=260\degree`

than find the value of angle B

Step-by-step explanation:

Value of arcADB is

`arcADB=360\degree-arcACB=360\degree-260\degree=100\degree`

Now to find the angle B

`\angle B=(1)/(2)arcADB=(1)/(2)*100=50\degree`

Final answer:

a
