median: The number that occurs in the middle after arranging in ascending order of magnitude
;13 13
since both appeared in the middle,you add it and divide by 2
13+13/2
26/2
13
;The median is 13
Zeros do not count as a sigfig so when you do something like this problem just include the numbers until you hit your significant figure limit and then substitute zeros where you can. 20000

Answer:
The correct answer is first option m<2 + m<3
Step-by-step explanation:
From the figure we can see a triangle with angles, <1, <2 and <3
By angle sum property we can write,
m<1 + m< 2 + m<3 = 180°
m<1 = 180 - (m<2 + m<3) ----(1)
Also we know that, <1 and <4 are linear pairs
m<1 + m<4 = 180°
m<1 = 180 - m<4 ---(2)
Compare (1) and (2) we get
m<4 = m<2 + m<3
