Question

please ans this question ​

Answer 1

z = 180 - 30 = 150

x = 180 - 90 = 90

third angle of triangle = 180 - (30+90) = 60

y = 180 - 60 = 120

x + y + z = 150 + 90 + 120 = 360

Note - The sum of this angles is always equals to 360. If the values of angle of triangle changes the sum of this angle remains same 360

Answer 2

Answer:

x = 180 - 90 ( linear pair)

= 90°

z = 180- 30

= 130°

30 + 90 + a = 180. ( angle sum property)

120 + a = 180°

a = 180 - 120

= 60°

y = 180 - 60 ( linear pair )

= 120°
