Hey friend ...

it's easy ...

•°•<AOC=130°{given )_______1)

and <AOB=180° (from linear pair )-----2)

now. ..<AOC+<BOC=<AOB {we can write }

(given } and from 1 and 2 we get .

130°+<BOC=180°

<BOC=50°

<BOC=2×<BDC(According to this theorem )

[•°•the angle substances by an arc at the centre is twice the angle subtended on the remaining part of the circle ]

So. BOC=x°=50°/2=25 °
Answer

Hope it helps you..!
