Question

How do you convert 45°50'50" to decimal degree notation?

Answer 1

Remember every minute `'` is `1//60`th of a degree and every second `''` is `1//60`th of a minute.

Step 1: seconds to minutes
`50''=50//60=0.8333...'`

Step 2:
Add the `50'`

Step 3: minutes to degrees
We now have `50.8333...'=50.8333...//60=0.8472... ^0`

Step 4:
Add the `45^0`

Answer :
`45.8472...^0`
