Answer:
x=90
( straight line angle = 180)
z=180-45=135 ( sum of straight angle = 180)
y= 45+90=135 ( external angle = sum of two opposite angle)
x+y+z=90+135+135= 360

Step-by-step explanation:
value of z
It is linear pair so 180-x=45
x=45-180=135=z
value of x=90
value of y
45+90+y'=180
y'=180-135
=45
value of y
180+45= 225
