BRAINLIEST!! Does the construction demonstrate how to copy a segment correctly by hand?

Yes; the compass was kept at the same width as segment AB to create the arc from point C.
Yes; a straightedge was used to create ray C.
No; the compass was not kept at the same width as segment AB to create the arc from point C.
No; a straightedge was used to create ray C.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
