Presentation transcript:

First, convert 0.125° into minutes and seconds. Convert Between DMS and Decimal Degree Form A. Write 329.125° in DMS form. First, convert 0.125° into minutes and seconds. 329.125° = 329° + 1° = 60' = 329° + 7.5' Simplify. Next, convert 0.5' into seconds. 329.125° = 329° + 7' + 1' = 60" = 329° + 7' + 30" Simplify. Therefore, 329.125° can be written as 329°7'30". Answer: 329°7'30" Example 1

B. Write 35°12'7'' in decimal degree form to the nearest thousandth. Convert Between DMS and Decimal Degree Form B. Write 35°12'7'' in decimal degree form to the nearest thousandth. Each minute is of a degree and each second is of a minute, so each second is of a degree. 35°12'7" = 35o + 12' Example 1

Therefore, 35°12'7" can be written as about 35.202°. Convert Between DMS and Decimal Degree Form ≈ 35° + 0.2 + 0.002 Simplify. ≈ 35.202° Add. Therefore, 35°12'7" can be written as about 35.202°. Answer: 35.202° Example 1

Write 141.275° in DMS form. A. 141°12'4.5" B. 141.2°45'0" C. 141°4'35" Example 1
