Answer:

3rd option: x= 40

4x°= 180° -20°

<em>Simplify</em><em>:</em>

4x°= 160°

<em>Divide</em><em> </em><em>by</em><em> </em><em>4</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

x°= 40°

Sasha is bisecting a segment. First, she places the compass on one endpoint, opens it to a width larger than half of the segment
ycow [4]

Her next step is to repeat the last process of drawing those two arcs. However, they will be mirrored since she swapped endpoints.

Check out the diagram below. Figure 1 is what she already has. Figure 2 is what happens after completing the next step. The red and blue arcs intersect to help form the endpoints of the perpendicular bisector. I used GeoGebra to make the diagrams.
