Question

Add:

$63°45\text{'}28\text{'}\text{'}$ and $85°50\text{'}45\text{'}\text{'}$

Answer 1

Step 1: Add seconds

$28\text{'}\text{'}+45\text{'}\text{'}=73\text{'}\text{'}=1\text{'}13\text{'}\text{'}$

Step 2: Add minutes

$45\text{'}+50\text{'}=95\text{'}=1°35\text{'}$

Step 3: Add degrees

$63°+85°=148°$

Step 4: Combine results of Step 1, Step 2 and Step 3

$1\text{'}13\text{'}\text{'}+1°35\text{'}+148°=149°36\text{'}13\text{'}\text{'}$

Hence, the final sum is $149°36\text{'}13\text{'}\text{'}$.
