Step-by-step explanation:

angle ADC=360-(45+35+50)

=360-130

=230 degree

\huge\boxed{Answer}

दिया है :-

Angle B = 45°

Angle C = 50°

Angle A = 35°

सिद्ध करना है :-

Determine the value of x

रचना :-

रेखा CD को E तक आगे बढ़ाया ।

हल :-

∆BCE में ,

Angle B + Angle C + Angle BEC = 180°

45° + 50° + Angle BEC = 180°

Angle BEC = 180° - 95°

Angle BEC = 85°

अब ,

Angle AED = 180° - 85° = 95°

AED में ,

Angle A + Angle AED + Angle D = 180°

35° + 95° + Angle D = 180°

Angle D = 180° - 130°

= 50°

अतः Angle X + Angle D = 180°

Angle X = 180° - 50°

Angle X = 130°
