Question

Find x+y+z in the following figure​

Answer 1

Step-by-step explanation:

z=180°-30° ( linear pair)

z= 150°

y= 90° +30° ( exterior property of triangle)

y=120°

x= 180°-90° ( linear pair)

x= 90°

= x+y+z

= 90°+120° +150°

= 360°

=x+y+z= 360°

Answer 2

Answer:

x= 90°, y= 120°, z= 150°

Step-by-step explanation:

Here

90 + x = 180° ------ linear pair

so, x= 180- 90

x = 90°

Similarly,

the remaining angle of triangle is 60° (sum of all angles of a triangle is 180°

y= 180 - 60

y= 120

z= 180- 30

z= 150°
