Question

Find the value of the angles a,b and c in the following figure​

Answer 1

Answer:

According to me

b = 25° ( Vertically Opposite Angles )

a = 180° - 25° = 155°

c = a = 155°

Answer 2

We need to Find,

• Values Of a,b and c.

Solution :-

25° + a° = 180° (Linear Pair).

➙ a° = 180 – 25°

➙ a° = 155°

Now, Calculating b.

a° + b° = 180° (Linear Pair).

➙ 155° + b° = 180°

➙ b = 180 – 155°

➙ b = 25°

Now, Calculating c.

25° + c° = 180° (Linear Pair).

➙ c° = 180 – 25°

➙ c° = 155°

Verification :-

a° + b° + c° + 25° = 360° (Whole Angle)

➙ 155° + 25° + 155° + 25° = 360°

➙ 180° + 180° = 360°

➙ 360° = 360°

LHS = RHS.

Hence, Verified.

Therefore,

• a° = 155°
• b° = 25°
• c° = 155°
