Question

in the adjoining figure find X + Y + Z​

Answer 1

Answer:

90+x=180. {linear pair}

x=180-90

x= 90

70+y=180. (linear pair)

y=180-70 = 110

90+70+a=180 (angle sum property of triangle)

160+a=180

a=180-160

a= 20

Answer 2

Answer:

Step-by-step explanation:

To find "y" :-

70°+y = 180°         (linear pair)

⇒ y = 180°-70°

⇒y = 110°

To find "x" :-

90°+ x = 180°    (linear pair)

x = 180°-90°

x = 90°

To find "z" :-

z = 90° + 70° (Exterior angle of a triangle is equal to the sum of opposite interior angles)

z = 160°
