Question 118669: Hello,
I am a freshman student having problems in goemetry. It would be wonderful if I could have a little extra help on a few problems. I would greatly appreciate it. :) Here is my first problem.
A calculation shows that an angle has a measure of 113.05 degrees.
This angle can be written in the form A B', measured in degrees and minutes.
What is the sum of A and B?

Note: In the second sentence the A has a degree symbol after it.

This is how far I got into the problem. 113 + ?/60 + ?/ 3600
