What is the reference angle of 240?A 240-degree angle is between 180 and 270 degrees, so its terminal side is in QIII. Do the operation indicated for that quadrant. Subtract 180 from 240. You find that 240 – 180 = 60, so the reference angle is 60 degrees.
Article first time published onWhat type of angle is 210?
Reflex Angle: An angle whose measure is more than 180° but less than 360° is called a reflex angle. ∠AOB shown in the above figure is 210°. So, ∠AOB is a reflex angle.

Trigonometry Examples The resulting angle of 225° 225 ° is positive and coterminal with −135° – 135 ° .
How are radians measured?
One way to measure angles is in radians. To define a radian , use a central angle of a circle (an angle whose vertex is the center of the circle). One radian is the measure of a central angle that intercepts an arc s equal in length to the radius r of the circle.
What is the terminal side?
Definition of terminal side : a straight line that has been rotated around a point on another line to form an angle measured in a clockwise or counterclockwise direction — compare initial side.
How do you solve tan 150?
For tan 150 degrees, the angle 150° lies between 90° and 180° (Second Quadrant). Since tangent function is negative in the second quadrant, thus tan 150° value = -1/√3 or -0.5773502. . . Since the tangent function is a periodic function, we can represent tan 150° as, tan 150 degrees = tan(150° + n × 180°), n ∈ Z.
What is the reference angle of 4 radians?
QuadrantReference angle for θ1Same as θ2180 – θ3θ – 1804360 – θ
How do you find the exact value of sin 150?
The value of sin 150 degrees can be calculated by constructing an angle of 150° with the x-axis, and then finding the coordinates of the corresponding point (-0.866, 0.5) on the unit circle. The value of sin 150° is equal to the y-coordinate (0.5). ∴ sin 150° = 0.5.

How do you find two Coterminal angles in radians?
To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360° if the angle is measured in degrees or 2π if the angle is measured in radians .
Are 180 and 540 Coterminal angles?
Trigonometry Examples The resulting angle of 180° 180 ° is positive, less than 360° 360 ° , and coterminal with 540° 540 ° .

What is a 270 angle?
270 Degree Angle This is an example of a “reflex angle,” which is any angle that measures between 180 and 360 degrees. A 270 degree angle goes 3/4 of the way around a circle, and forms a right angle with one vertical and one horizontal line.
What is the Coterminal angle of 405?
For example 45°, 405° and -315° are coterminal angles because all three angles have the same initial side (the x axis) and they share a same terminal side.
