The result can be shown in multiple forms. Exact Form:It is important to use the three reference angles from the special right triangles to work through ... 225, and 240. Lastly, for quadrant 4 subtract 30, 45, and 60 from 360 to create 330, 315, and ...A 180-degree angle is called a straight angle. Angles that are exactly 90 degrees are called right angles, while those that are between 0 and 90 degrees are called acute. Angles that are between 90 and 180 degrees are considered obtuse.This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.

Apr 14, 2022 · The reference angle of -225° is 45° Reference Angle of 1°-360° The reference angle of 1° to 90° equals the initial angle. For example, a reference angle of 1° is 1°, 8° is 8°, a reference angle of 55° is 55°, and so on up to 90°. The reference angles of 91° – 360° are listed in the table below. For sin 150 degrees, the angle 150° lies between 90° and 180° (Second Quadrant ). Since sine function is positive in the second quadrant, thus sin 150° value = 1/2 or 0.5. Since the sine function is a periodic function, we can represent sin 150° as, sin 150 degrees = sin (150° + n × 360°), n ∈ Z. ⇒ sin 150° = sin 510° = sin 870 ...

Tan values are positive in the 1st and 3rd quadrants and negative in the 2nd and 4th quadrants. However, they are all linked to the angle in the first quadrant. (θ) 330° = 360° − 30°. tan30° = 1 √3. tan330° = −tan30° = − 1 √3. Answer link. Find tan 330 deg Ans: -sqrt3/3 On the trig unit circle, tan 330 = tan (-30 + 360) = tan ...Reference angles. A reference angle is an acute angle (<90°) that can be used to represent an angle of any measure. Any angle in the coordinate plane has a reference angle that is between 0° and 90°. It is always the smallest angle (with reference to the x-axis) that can be made from the terminal side of an angle. The figure below shows an ...…
