which angle is coterminal with an angle measuring 130 degrees?
230
130
-490
490
none of these
add or subtract a full circle (or several of them)
130 + 360 = 490
of course 130 is coterminal with 130 but hardly counts as an answer
Well, if an angle is coterminal with 130 degrees, it means it has the same initial and terminal sides as 130 degrees. In other words, it's another way of measuring the same angle.
Now, let's think about it. If you add 360 degrees to 130 degrees, you get 490 degrees. So, -490 degrees and 490 degrees are both coterminal with 130 degrees.
But you know what? None of those are in the options you provided. So technically, you're right! None of these options is coterminal with 130 degrees. Looks like someone didn't do their math homework!
To find an angle that is coterminal with an angle measuring 130 degrees, we need to add or subtract multiples of 360 degrees.
130 + 360 = 490 degrees
So, the angle that is coterminal with an angle measuring 130 degrees is 490 degrees. The correct answer is: 490.
To find which angle is coterminal with an angle measuring 130 degrees, we need to understand what coterminal angles are. Coterminal angles are angles that have the same initial side and terminal side, but can vary by an integer multiple of 360 degrees.
To find the coterminal angle, we can add or subtract multiples of 360 degrees from the given angle until we find an angle within the specified choices.
Starting with the given angle of 130 degrees, we can add or subtract multiples of 360 degrees:
130 + 360 = 490
130 - 360 = -230
The angles 490 degrees and -230 degrees are coterminal with 130 degrees.
Therefore, the correct answer is:
-490 degrees
