Reference angle of 330
reference angle. 9. 2 3S J The angle J is on the positive y-axis. Thus, the angle J does not have a reference angle. Back to Topics List 2. THE REFERENCE ANGLE OF THE SPECIAL ANGLES The reference angle of the Special Angles of , 6 7, 6 5, 6 S S S r r r and 11S r is 6 S. The reference angle of the Special Angles of , 4 5, 4 3, 4 S S S r r r and ... The angle 135° has a reference angle of 45°, so its sin will be the same. Checking on a calculator: sin(135) = 0.707. This comes in handy because we only then need to memorize the trig function values of the angles less than 90°. The rest we can find by first finding the reference angle.

For example, if the given angle is 330°, then its reference angle is 360° – 330° = 30°. Example: Find the reference angle of 495°. Solution: Let us find the coterminal angle of 495°. The coterminal angle is 495° − 360° = 135°. The terminal side lies in the second quadrant. Thus the reference angle is 180° -135° = 45° Therefore ...Answer link. (5pi)/4 = 225^@.

If you know two angles of a triangle, it is easy to find the third one. Since the three interior angles of a triangle add up to 180 degrees you can always calculate the third angle like this: Let's suppose that you know a triangle has angles 90 and 50 and you want to know the third angle. Let's call the unknown angle x. x + 90 + 50 = 180 x ...Trigonometry. − 5π 6 - 5 π 6. To convert radians to degrees, multiply by 180 π 180 π, since a full circle is 360° 360 ° or 2π 2 π radians. (− 5π 6)⋅ 180° π ( - 5 π 6) ⋅ 180 ° π. Cancel the common factor of π π. Tap for more steps... −5 6 ⋅180 - …If you’re an avid angler, purchasing a fishing boat is likely on your radar. While new boats may have their appeal, there are significant benefits to consider when it comes to purchasing a used fishing boat.Coterminal angles are angles in standard position (angles with the initial side on the positive x x -axis) that have a common terminal side. For example 30° 30 ° , −330° − 330 ° and 390° 390 ° are all coterminal. To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360° 360 ° if the angle ...
sec(240) sec ( 240) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because secant is negative in the third quadrant. −sec(60) - sec ( 60) The exact value of sec(60) sec ( 60) is 2 2. −1⋅2 - 1 ⋅ 2. Multiply −1 - 1 by 2 2. −2 - 2. The reference angle is the positive acute angle that can represent an angle of any measure. The reference angle must be < 90 ∘ . In radian measure, the reference angle must be < π 2 . Basically, any angle on the x-y plane has a reference angle, which is always between 0 and 90 degrees. The reference angle is always the smallest angle that ... ….

The procedure to use the reference angle calculator is as follows: Step 1: Enter the angle in the input field. Step 2: Now click the button “Calculate Reference Angle” to get the result. Step 3: Finally, the reference angle for the given angle will be displayed in the output field.Answer and Explanation: 1 Become a Study.com member to unlock this answer! Create your account View this answer Given: tan(330∘) tan ( 330 ∘) The given angle lies in the fourth …If the terminal side is in the third quadrant, the reference angle is the angle minus 180∘ or π. If the terminal side is in the fourth quadrant, the reference angle is 360∘ or 2π minus the angle. In this example, the angle of 330∘ is in the fourth quadrant, so know that in order to find the reference angle, we must subtract the angle ...
We convert degrees to radians because radians provide a more natural and consistent unit for measuring angles in mathematical calculations and trigonometric functions.

In the figure above, drag A or D until this happens. If the angles are the same, say both 60°, they are obviously coterminal. But the angles can have different measures and still be coterminal.draw the reference angle of cos(-330) BUY. Trigonometry (MindTap Course List) 8th Edition. ISBN: 9781305652224. Author: Charles P.
