Feb 5, 2015

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
$50 ' ' = 50 / 60 = 0.8333 \ldots '$

Step 2:
Add the $50 '$

Step 3: minutes to degrees
We now have $50.8333 \ldots ' = 50.8333 \ldots / 60 = 0.8472 {\ldots}^{0}$

Step 4:
Add the ${45}^{0}$

$45.8472 {\ldots}^{0}$
