Hope this helped :)
Side BC is congruent to side DC. (That's what the hash marks mean.) Angle C is congruent with itself, and the right angles at B and D are all congruent.
Thus, you want to choose triangle names that show BC congruent to DC. The appropriate selection is the second one ...

ANSWER: 314.15 sq. cm
Step-by-step explanation:
Lid of a circular jar will be a circle.
Given,radius of the lid,r=10cm
Area=π*r*r
=3.1415*10*10 sq.cm
=314.15 sq cm (approximately)
Answer:
m∠AVF = 158°
Step-by-step explanation:
In the diagram attached,
m∠AVD = m∠BVE = m∠CVF = 90°
m∠CVD = 22°
∠AVB = ∠EVF
Since ∠AVD = ∠AVC + ∠CVD
Therefore, 90° = m∠AVC + 22°
m∠AVC = 90° - 22°
= 68°
Similarly, m∠CVF = m∠CVD + m∠DVF
90° = 22° + m∠DVF
m∠DVF = 68°
m∠AVC = m∠DVF = 68°
Now ∠AVF = ∠AVD + ∠DVF
= 90° + 68°
= 158°
