plz.tell fast it's very urgent.dont give irrelevant answers​

Answer 1

Answer:

x = 75°

y = 45°

Step-by-step explanation:

1. y = 180° - 135°       ( Linear Pair )

     = 45°

2. x + y + 60° = 180° ( Angle Sum Property of a Triangle )

   x + 45° + 60° = 180°    ( y = 45, Proved)

   x + 105° = 180°

   x = 180° - 105° = 75°

Therefore x = 75° and y = 45°

Answer 2

Answer:

x= 75 degree and y=45 degree

Step-by-step explanation:

because sum of opposite inside angles of of triangle is the outer angle. so, A +B =135 degree = 60 degree + B = 135 degree . so that B = 135 degree-60 degree so that x= 135-60 = 75 degree .

and y=45 degree because A+B+ y = 180 degree . so 60+75+y =180 degree. hence 180-

135=45 degree.
