Answer 1

Answer:

heya❤️

here's your answer, mate.......

7. (a)

{ Please also refer to my attachment✔️ }

/_1 = /_2 .......(vertically opposite angles)

97° = /_2

/_3 = /_4 .......(vertically opposite angles)

/_ 1 + /_3 = 180° .......(linear pair)

97° + /_3 = 180°

/_3 = 180° - 97°

/_3 = 83° .........(1)

As, /_3 = /_4 ........(proved above)

So, /_4 = 83° ........(From equation - (1).

Thus, all angles are :-

• /_1 = 97°
• /_2 = 97°
• /_3 = 83°
• /_4 = 83°.

(b)

In the same way as first was done........

I hope this detailed explanation would have helped you.....!! ☺️✨

Answer 2

a) <AOC=<DOB ( VOA)

<AOD=<COB(VOA)

SO,

<AOC+<BOD+<COA+<DOB=360°

97°+<BOD+97°+<DOB=360°

194°+2<BOD=360°

2<BOD=360°-194°

2<BOD=166°

<BOD=166÷2

<BOD=83°

So,

97°+97°+83°+83°=360°

b)

<ROP=<QOS(VOA)

<ROQ=<POS(VOA)

14+14+2<ROQ=360°

2<ROQ=360°-28°

2< ROQ=332°

<ROQ=332°÷2

ROQ=166°

So,

14°+14°+166°+166°=360°
