Add 26°34' and 51°22'.

To add 26°34' and 51°22', we need to add the degrees separately from the minutes.

First, add the degrees: 26° + 51° = 77°.

Next, add the minutes: 34' + 22' = 56'.
Since there are 60 minutes in a degree, we need to simplify the sum by converting some minutes into degrees if necessary.

56' = 1°, since 60' = 1°.

Finally, add the degrees we converted: 77° + 1° = 78°.

Therefore, 26°34' + 51°22' = 78°.
