. Mark and label any point on the arc.
Step-by-step explanation:
<u>Step for copying a Line Segment PQ</u>
- Mark a point R that will be on the new line
- Place the compass on one end of the line
- Adjust the compass width to the other end of the line
- Without moving the compass width, move the compass to R
- Draw an arc near where the end of the new line should be
- Pick a point S on the arc to be the end point of the new line
- Draw a straight line between R and S
Therefore, the next step is to <u>Mark and Label any point on the arc.</u>
Answer:
x=30
Step-by-step explanation:
So we know its a supplementary angle which is angles athat add up to 180 degrees since its a straight line.
Make an equation: 60+60+2x=180COmbine like terms
120+2x=180
subtract 120 on both sides
2x=60
x=30
