Describe how to use a protractor and straightedge to draw a 130° angle. then describe how to
bisect the angle using a compass.
a)
use the straightedge to draw a ray center the protractor at the endpoint on the left of the ray
use the outside scale of the protractor to mark 130. use the straightedge to draw another
ray between the endpoint on the left of the ray and the mark at 130
place the compass point at the vertex of the 130-angle. draw an arc that intersects both sides
of the angle. use the straightedge to draw the line segment connecting the points where the arc
intersects each side of the ray.
b)
use the straightedge to draw a ray. center the protractor at the endpoint on the left of the ray,
use the inside scale of the protractor to mark 130. use the straightedge to draw another
ray between the endpoint on the left of the ray and the mark at 130
place the compass point at the vertex of the 130-angle. draw an arc that intersects both sides

Ascientist wants to use a model to present the results of his detailed scientific investigation. why would a model be useful? a )because the model makes the concepts easier to understand b) because the model is easy to put together and to use c) because the model prevents other scientists from asking questions d) because the model requires the audience to pay full attention to it i don't know what to choose because between a and d a is much more likely than d because it only wants to get the attention of the audience. i'm confuse.
