Question

Plz help!! :)

Find the measures of angles x, y, and z.

Answer 1

x = 40º

y = 50º

z = 130º

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 2

`x = 40 \\ y = 50 \\ z=130`

Explanation:

`x = 180 - 140`

`x = 40`

`y = 180 - (90 + 40)`

`y = 180 - 130`

`y = 50`

`z = 180-50`

`z = 130`
