Question

in figure if angle AOD=135*,then find angle BOC ​

Answer 1

Answer:

45 degree

Step-by-step explanation:

Given: in figure if angle AOD=135*,then find angle BOC ​.

The quadrilateral ABCD is outside the circle with centre o.

The opposite sides of a quadrilateral subtend supplementary angle at the centre.

Two angles are supplementary when both angles add up to 180 degree.

From this theorem we get

angle BOC + angle AOD = 180

       BOC + 135 = 180

        BOC = 180 - 135

      Angle  BOC = 45 degree

Answer 2

AOD+BOC=180 [OPPOSITE SIDES OF A QUAD CIRCUMSCRIBING A CIRCLE SUBTEND SUPPLEMENTARY ANGLES AT THE CENTRE]

THEREFORE
135+BOC=180

BOC=45
