Question

Find angle X in the angle diagram.

Answer 1

80°

Explanation:

160 is vertically opposite the x and 80, which means they have the same value. This makes x+80=160.

This can be solved to x=80.

Answer 2

80*

Explanation:

Angle x + 80* add up to the vertical angle of 160*

So, 160* = x + 80*

80* = x
