Answer:
(B)m∠AVC+m∠CVB=m∠AVB
Step-by-step explanation:
Given: It is given that a point C is inside ∠AVB and ∠AVC=39° and ∠CVB=23°.
To find: m∠AVC+?=m∠AVB
Solution: It is given that a point C is inside ∠AVB and ∠AVC=39° and ∠CVB=23°, then
From the figure, we can see that C is inside ∠AVB, therefore ∠AVB is divided into two parts that is ∠AVC and ∠CVB, thus
m∠AVC+m∠CVB=m∠AVB
⇒39°+23°=62°
Hence proved.
Hence, option B is correct.
