Answer:-
x = 59
Step-by-step explanation:-
∠BCD + ∠ACD = 180° [Linear pair]
⇒ (2x + 4)° + (x - 1)° = 180°
⇒ 2x° + 4° + x° - 1° = 180°
⇒ 3x° + 3° = 180°
⇒ 3x° = 177°
⇒ x° = 177° ÷ 3
⇒ x° = 59°
⇒ x = 59
Answer⇒ x = 59
Verification:-
(2x + 4)° + (x - 1)°
- Substitute x = 59
(2(59) + 4)° + (59 - 1)°
⇒ (118 + 4)° + (58)°
⇒ (122)° + 58°
⇒ 122° + 58° = 180° = RHS
Hence, verified.
