Question

* In the given figure find the qvalus of x​

Answer 1

Step-by-step explanation:

A/Q x + 20 + x + 3 + x + 7 = 180⁰

3x = 180⁰ - 30⁰

3x = 150⁰

x = 50⁰ Ans .

Answer 2

Hey Niranjanviswams !

Answer:

x = 50°

Step-by-step explanation:

Concept :

All the three angles drawn in the figure must add upto 180°. ∵ It is a straight line.

Procedure :

(x + 3°) + (x + 20°) + (x + 7°) = 180°

⇒ (x + x + x) + (3° + 7° + 20°) = 180°

⇒ 3x + 30° = 180°

⇒ 3x = 150°

∴ x = 50°

The left Angle = 50° + 3° = 53°

∠DBC = 50° + 20° = 70°

The right Angle = 50° + 7° = 57°

Confirmation :

53° + 70° + 57°

⇒ 180°

Hence we did it correctly.

Thanks !
