Find the sum.

20° 15' 18''
30° 41' 32''
2° 30' 15''
+

add the 3 columns separately

 20 +30 +2 = 52 degrees

15+41+30 =86 minutes

18 +32 +15 = 65 seconds

 since minutes is greater than 60 subtract 60 from 86 and add 1 to the degrees

 now you have 52+1 - 53 degrees

and 86-60 = 26 minutes

since seconds is also greater than 60, subtract 60 from 65 and add 1 to the minutes

26+1=27

65-60 = 05 seconds

 so the sum is 53 degrees 27 minutes 05 seconds

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.

i believe the correct answer is b.
