Answer:

x = 40º

y = 50º

z = 130º

Step-by-step explanation:

Recall that supplementary angles add up to 180º. Also, all angles in a triangle add up to 180º.

angle x

180 - 140 = 40º = xº

angle y

90 + 40 = 130

180 - 130 = 50º = yº

angle z

180 - 50 = 130º = zº

Answer:

[tex]x = 40 \\ y = 50 \\ z=130[/tex]

Step-by-step explanation:

[tex]x = 180 - 140[/tex]

[tex]x = 40[/tex]

[tex]y = 180 - (90 + 40)[/tex]

[tex]y = 180 - 130[/tex]

[tex]y = 50[/tex]

[tex]z = 180-50[/tex]

[tex]z = 130[/tex]
