Answer 1

Answer:

7:- Let angle AOC be x

So, Aoc = Boc = x

A/Q,

Aoc + Boc = 180°

x + x = 180°

2x = 180°

x = 90°.

Aoc = Boc = 90° proved.

8:- Let Cod = x

A/Q,

Aoc + x + Bod = 180°

x + 70° = 180°

x = 180° - 70°

x = 110° ans.

Answer 2

Step by 7:- Let angle AOC be x

So, Aoc = Boc = x

A/Q,

Aoc + Boc = 180°

x + x = 180°

2x = 180°

x = 90°.

Aoc = Boc = 90° proved.

8:- Let Cod = x

A/Q,

Aoc + x + Bod = 180°

x + 70° = 180°

x = 180° - 70°

x = 110° ans.
