Determine the reference angle of 1387°
WebFirst find a coterminal angle between 0° and 360°. Divide 1387º by 360 to get a quotient of about 3.9. Begin by subtracting 360° three times. 1387° – 3(360°) = 307°. The reference … WebApr 30, 2015 · It is always possible to add, or subtract, 360° to an angle to obtain an equivalent one. The symbol ≡ in the following passages is not a real =, but only an equivalent symbol. −960° ≡ − 960° + 360° ≡ − 600° ≡ − 240° ≡ 120°. And 120∘ is 60∘ from the horizontal, so the reference angle for 120∘ and for the original ...

WebSep 14, 2024 · 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’s ... WebMar 27, 2024 · Figure 2.3.2. 4. Now, let's determine the quadrant in which − 745 ∘ lies and hence determine the reference angle. Since our angle is more than one rotation, we need to add 360 ∘ until we get an angle whose absolute value is less than \) 360 ∘: − 745 ∘ + 360 ∘ = − 385 ∘, again − 385 ∘ + 360 ∘ = − 25 ∘. Now we can plot ...
WebTerminal side is in the second quadrant. When the terminal side is in the second quadrant (angles from 90° to 180° or from π/2 to π), our reference angle is 180° minus our given angle. So, you can use this formula. Reference angle° = 180 - angle. For example: The reference angle of 125 is 180 - 125 = 55°.
