Question no.7 plz ans it...

Answer 1

Answer:

(c) 100°

Step-by-step explanation:

●L BAC = 80°

●L OBA = L OCA = 90° (Radius Tangent Theorem)

●In quadrilateral OBAC, By Angle Sum Property

L BAC + L OBA + L OCA + L BOC = 360°

80° + 90° + 90° + L BOC = 360 °

260° + L BOC = 360°

L BOC = 360°-260°

L BOC = 100 °
