WebSupplementary angles add up to 180° - example: 50° & 130° are supplementary (added together, they form a straight line) Two facts: (1) 90° comes before 180° on the number line (2) "C" comes before "S" in the alphabet You can use this to help you remember! 90° goes with "C" for complementary so complementary angles add up to 90° WebMar 14, 2024 · How do we determine coterminal angles mathematically? Simply adding or subtracting 360 degrees to an angle repeatedly will create values of coterminal angles. …
WebMar 27, 2024 · The angle −90^{\circ}\) is coterminal with \(270^{\circ}\). Therefore the ordered pair is (0, -1) and the cosine value is 0. Figure \(\PageIndex{2}\) We can also use our knowledge of reference angles and ordered pairs to find the values of trig functions of angles with measure greater than 360 degrees. Example \(\PageIndex{1}\)
WebTwo angles are coterminal if the difference between them is a multiple of 360° or 2π. Example: Determine if the following pairs of angles are coterminal. a) 10°, 370°. b) –520°, 200°. c) –600°, –60°. Solution: a) 10° – 370° = –360° = –1 (360°), which is a multiple of 360°. So, 10° and 370° are coterminal. china tradition of medication with needeleWebStart the solution by writing the formula for coterminal angles. Let ∠θ = ∠ɑ = ∠β = ∠ɣ.
