Answer 2

By using vertically opposite angles property,

Angle x = 65°

So, angle x = 65°

Figure = 360°

65 × 2 = 130°

360 - 130 = 230°

Again by using vertically opposite angles property,

Angle y = Angle z

Which means,

230 ÷ 2 = 115° (either of angle y and z)

So, angle y = 115°

And also angle z = 115°

Angle x = 65°

Angle y = 115°

Angle z = 115°
