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]

Angles on a straight line add up to 180 so take 91 away from 180 to give you 89 i guess ^^; i hope that helps somewhat

Need help presenting this solution on and number line and in interval notation. (I’m absolutely clueless haha)

Since the number is a fraction make a number line using fractions. The inequality sign includes being equal to, so add a solid dot on -5/2 and since x is less than that, draw an arrow pointing to the left.

See attached drawing.

For interval notation since x can be any number less than or equal to -5/2 it would be written as (-∞, -5/2]
