If ∠BOD = 63°, then ∠BOC = Let us draw the following diagram showing two lines AB and CD intersecting each other at a point O. Let the required angle ∠BOC measures x°. Also, ∠BOCand ∠BODform a linear pair. Therefore, their sum must be equal to 180°. That is, ∠BOC +∠BOD = 180° It is given that. ∠BOD = 63°Substituting, this value above, we get: ∠BOC +63° = 180° ∠BOC = 180° - 63° ∠BOC =117° Concept: Introduction to Lines and Angles Is there an error in this question or solution? |
