Triangle

∠MNL = ∠MLN = 25°

∠LMN = 180° - 25° - 25°
∠LMN = 130°

Parallelogram

∠LKQ = ∠LMQ = 50°

x =  ∠LMN - ∠LMQ
x = 130° - 50°
x = 80° (answer)

∠ LMQ = ∠ LKQ 50°

∠ LMN = 180° - 25° - 25°
            = 130°

x° = 130° - 50°
     = 80°
sy x fhm macam mana 180 tu
btw, thanks
jumlah ketiga sudut pada segitiga adalah 180
sama-sama
