Find the sum {will give brainliest} 20pt

Hello from MrBillDoesMath!

53 degrees, 27 minutes, 5 seconds

(53 goes in the first box on the left; 27 in the middle box; 5 in the rightmost box)

Discussion:

Sum of the degrees = 20 + 30 + 2 = 52 degrees

Sum of the minutes = 15 + 41 + 30 = 86 minutes = 1 degree, 26 minutes

Sum of the seconds = 18 + 32 + 15 = 65 seconds = 1 minute, 5 seconds

So adding all of this up gives a grand sum of

(52 degrees) + ( 1 degree, 26 minutes) + (1 minute, 5 second) =

53 degrees, 27 minutes, 5 seconds

Thank you,

MrB

52°   86'   65"

Step-by-step explanation:

20° + 30° = 50°

50° + 2° = 52°

15' + 41' = 56'

56' + 30' = 86'

18" + 32" = 50"

50" + 15" = 65"
