Reference angle of 330
Are you in the market for a used Lexus RX 330? If so, you’re in luck. The Lexus RX 330 is one of the most reliable and luxurious SUVs on the market. It has a great combination of performance, comfort, and style.The reference angle is the amount of rotation more than 180 the 210 extends into the third quadrant. So the reference angle is calculated by subtracting 180 from 210 . So the reference angle indicated by the the red arc is 210 - 180 = 30 . So that's the answer. The reference angle is always the acute angle between the terminal side and the x-axis. To calculate sine, cosine, and tangent in a 3-4-5 triangle, follow these easy steps: Place the triangle in a trigonometric circle with an acute angle in the center. Identify the adjacent and opposite catheti to the angle. Compute the results of the trigonometric functions for that angle using the following formulas: sin (α) = opposite ...

Without using a calculator, compute the sine and cosine of 330° by using the reference angle. Give the sine and cosine as reduced fractions or with radicals. Do not use decimals. a. What is the reference angle? b. In what quadrant is this angle? sin(330° ) = _____ cos(330° ) = _____ Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the third quadrant. Step 2. The exact value of is . Step 3. The result can be shown in multiple forms. Exact Form: Decimal Form:360° - 330° = 30°, so the reference angle is 30°. 330° is in quadrant IV, and cosine is positive in quadrant IV, so: Properties of the cosine function. Below are a number of properties of the cosine function that may be helpful to know when working with trigonometric functions.A reference angle, denoted θ ^, is the positive acute angle between the terminal side of θ and the x -axis. The word reference is used because all angles can refer to QI. That is, memorization of ordered pairs is confined to QI of the unit circle. If a standard angle θ has a reference angle of ˚ 30 ˚, ˚ 45 ˚, or ˚ 60 ˚, the unit circle ...
