Line \(\bar{DG}\) is a straight line, that means that it its angle is \(180˚\). That means 2 angles must add up to \(180˚[tex]. This is called the complementary angle property. An example is below as an image.
If the two angles must add up to [tex]180˚\), and one is \(92˚\), you can find \(\measuredangleJAR\) by doing:
180-92=
[tex]88˚/tex]
