What is cos 120 degree value?
-½
Value of Cos 120 is -½.
What is the sin and cos of 120?
Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. We know that the value of cos 30 degrees is √3/2. Therefore, sin 120° = √3/2.
How do you find the exact value of sin 120?
How to Find the Value of Sin 120 Degrees? The value of sin 120 degrees can be calculated by constructing an angle of 120° with the x-axis, and then finding the coordinates of the corresponding point (-0.5, 0.866) on the unit circle. The value of sin 120° is equal to the y-coordinate (0.866). ∴ sin 120° = 0.866.
What is the reference angle for 120 degrees?
60°
Reference angle for 120°: 60° (π / 3)
How do you find the exact value of sin 120 degrees?
How do you find the reference angle for 120 degrees?
Reference angle for 120°: 60° (π / 3)
What is the angle of 120?
The angle measure ranges from 90° to 180°. An obtuse angle can also be found out if we have the measure of the acute angle. In the picture above, line segment DO intersects line segment OQ at point O and forms an angle DOQ measuring 120°. Thus, it is an obtuse angle.
What is the supplement of 120?
The supplementary angle of 120° is 60°.
How do you bisect a 120 degree angle?
Expert-verified answer question
- Draw an angle of ∠AOB of 120°.
- Draw an arc from point O. This arc will cut the ray OA at any point C and ray OB at any point D.
- Draw two arcs of the same radii from the points C and D as centres.
- Join the point O to the point M by a ray OM.
- m∠AOM = m∠BOM =
What is the supplementary angle of 125?
ANSWER: The supplement of 125 degrees is 55 degrees.
What is the bisector of 120?
Answer. Make a 60 degree angle and with the same radius make another semicerclefrom the 60 degree point to make it intersect with the line from where you want to draw the 120 angle (starting point) . The point gained when connected to the starting point will give 120 deree….
