Question

Write if angles are complementary, supplementary, or adjacent. Find the value of x in eachfigure.1.120

Answer 1

1. 120 deg and x are supplement angles, as they add 180 degrees.

`\begin{gathered} 120+x=180 \\ x=180-120=60 \end{gathered}`

2. In this case, 119 deg and x are opposed by the vertex, so they have the same value:

`x=119`
