Find the value of the unknown angles in the given figures​

Answer»

ong>Answer:

x = 55° (VERTICALLY opposite angles).

z + 112° = 180° (LINEAR PAIR, BD is a STRAIGHT line)

=> z = 180° - 112° = 68°

x + y + z = 180° (Sum of all angles in a traingle)

=> 55° + y + 68° = 180°

=> y = 180° - 55° - 68° = 57°
