How to Calculate 90° - 47°49'32

Subtracting angles in degrees, minutes, and seconds requires careful handling of each component. Here's how to perform the calculation 90° - 47°49'32:

Formula for Angle Subtraction

When subtracting angles with degrees, minutes, and seconds, follow these steps:

  1. Subtract the degrees: 90° - 47° = 43°
  2. Subtract the minutes: 0' - 49' = -49'
  3. Subtract the seconds: 0" - 32" = -32"
  4. Adjust the negative minutes and seconds by borrowing 1 degree (which is 60 minutes) and 1 minute (which is 60 seconds)
  5. Final result: 42°10'28"

The result of 90° - 47°49'32 is 42°10'28". This means the difference between the two angles is 42 degrees, 10 minutes, and 28 seconds.

Step-by-Step Calculation

Let's break down the calculation of 90° - 47°49'32 step by step:

  1. Subtract the Degrees

    First, subtract the degrees component:

    90° - 47° = 43°

  2. Subtract the Minutes

    Next, subtract the minutes component. Since we have 0 minutes in the first angle, we need to borrow from the degrees:

    0' - 49' = -49'

    We borrow 1 degree (60 minutes) from the 43° result:

    43° becomes 42°

    0' becomes 60'

    Now subtract: 60' - 49' = 11'

  3. Subtract the Seconds

    Finally, subtract the seconds component. Again, we have 0 seconds in the first angle, so we need to borrow from the minutes:

    0" - 32" = -32"

    We borrow 1 minute (60 seconds) from the 11' result:

    11' becomes 10'

    0" becomes 60"

    Now subtract: 60" - 32" = 28"

  4. Final Result

    Combining all the components, we get:

    42°10'28"

Interpreting the Result

The result of 42°10'28" means that the angle difference between 90° and 47°49'32 is 42 degrees, 10 minutes, and 28 seconds. This is equivalent to:

  • 42.1744° in decimal degrees (42 + 10/60 + 28/3600)
  • 151,428" in total seconds (42×3600 + 10×60 + 28)

Practical Interpretation

This calculation is useful in various fields such as:

  • Navigation and surveying
  • Architecture and construction
  • Engineering measurements
  • Trigonometry problems

Common Uses of Angle Subtraction

Subtracting angles is a fundamental operation in many practical applications:

  • Calculating the difference between two compass bearings
  • Determining the angle between two lines in a diagram
  • Adjusting angles in mechanical components
  • Solving trigonometric problems
  • Converting between different angle measurement systems
