Answer 1

❇️ consider AB//CD

Angle ADC= 50°

Angle BAD = 180- 50 = 130°

Angle BCD = 70°

Angle CBA = 180-70= 110°

Angle E = 180-(Angle A +Angle B)/2 = 60°

Angle G= 180- ( Angle D +Angle C)/2 =

120°

Angle H =180- ( Angle B+ Angle C)/2=

90°

Angle F = 180-(Angle A + Angle D)/2= 90°

Hence Proved Quadrilateral EFGH is a Cyclic

Angle E +Angle F +Angle G + Angle H= 360°

Answer 2

Meiko bas itna hi aata hai

Pta nhi sahi hai ya galat ^^"

Aur vo dusre wale mein apna name dekho = IWonU xD xD
