Change 0.45° to equivalent minutes and seconds. Round to the nearest second if necessary.
konstantin123 [22]

0.45° in minutes is 27.36 minutes and in seconds is 21.6 seconds.

Why is it necessary to divide decimal degrees by 60 to obtain minutes and seconds?

  • In a complete rotation, circles and spheres have 360 degrees. One degree is divided into sixty minutes, and one minute is divided into sixty seconds.
  • You may see that your measurement is 91 full degrees plus 0.456 of a degree if you have 91.456 degrees.

How 0.45° is converted to equal minutes and seconds?

  • To convert 0.456 degrees to minutes, multiply 0.456*60 and you will get the answer as 27.36 minutes. You now have a total of 27 minutes and 0.36 of a minute.
  • To express 0.36 minutes seconds in decimal form, multiply 0.36*60 to get 21.6 seconds. You can round up to twenty two seconds because your decimal 0.6 is bigger than 0.5.

Find the value of x. Show your work.
yarga [219]

Answer:

x = 11

Step-by-step explanation:

∠BCE + ∠ECF = 180°

∴(10x + 15)° + 5x° = 180°

(15x + 15)° = 180°

15x = 180° - 15°

15x = 165°

x = 165°/15°

x = 11°
