Question

please any one tell ans​

Answer 1

X + Y + Z = 360°

pls mark me brainliest and follow me

Answer 2

let any variable d

1d +2d +3d = 180

6d = 180

d = 30

hence, all interior angles are as following :

(1.) 30 (2.) 60 (3) 90

as we know linear pair have sum of 180

so, x = 120

y = 90

z = 150

please follow me
