Determine the reference angle

Web1. If angle A is in quadrant I then the reference angle A r = A . 2. If angle A is in quadrant II then the reference angle A r = 180° - A if A is given degrees and A r = π - A if A is given in radians. 3. If angle A is in quadrant III then the reference angle A r = A - 180° if A is given degrees and A r = A - π if A is given in radians. 4. WebPrecalculus. Find the Reference Angle 345 degrees. 345° 345 °. Since the angle 345° 345 ° is in the fourth quadrant, subtract 345° 345 ° from 360° 360 °. 360°− 345° 360 ° - 345 °. …

WebFigure 1.5.4. 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 ... WebGoogle Classroom In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles. The hypotenuse of a right triangle is always the side opposite the right angle.
