Which of the following best describe perpendicular lines? a. lines that are not in the same plane b. lines that meet at a 90* angle c. lines that meet at a 45' angle d. lines that are coplanar and do not intersect

A line is said to be perpendicular to another line if the two lines intersect at a right angle. An angle is said to be a right angle if its measure is 90 degrees.

The question is asking us to select the option which best describes a perpendicular lines.Among all the options given option B states :Lines that meet at a 90* angle.

Option B is the right answer.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
