Question

Hlo guys
please answer question
The diagonals of a rectangle ABCD intersect at O if angle BOC is equal to 60 degree find angle ODA​

Answer 1

Answer:

In triangle BOC,

ang BOC +ang OCB+ang OBC= 180°

60°+2 ang OBC= 180° [as triangle OBC is an isocelestriangle, the base angles are equal]

2 ang OBC=180°-60

=120

ang OBC=120/2 °

ang OBC=60°

ang OBC=ang ODA

ang ODA=60°
