Answer:

no because there are also right angles. an obtuse angle can best be defined as an angle greater than 90 degrees and less than 180 degrees

Answer:

Ebony's definition is not valid.

Step-by-step explanation:

Obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

And acute angles measure more than zero degrees and less than 90 degrees.

We know that a right triangle is neither acute nor obtuse.

As Ebony has not mentioned right angles, so her definition is not valid.

Convert 17.47° to degrees, minutes, and seconds..
never [62]
For this question, this might help.
17.47 degrees is 17 + 0.47 degrees
If you are using minutes instead of decimal degrees, multiply the fraction by 60. So,

0.47 degrees * 60 minutes per degree= 28.2 minutes

Now you have 17 degrees 28.2 minutes but you can replace fractions of a minute with seconds
 
0.2 minutes * 60 seconds per minute= 12 seconds

So the answer for 17.47º is equal to 17º 28' 12".

I hope this helps.
