Quadrantal angle - math word definition - Trigonometry

2) The process known as _____ a triangle is used for calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known. solving 3) The three expressions, sin-1, cos-1, and tan-1 are called _____ trig functions and are used to find the measure of the acute angles of a right triangleFor an angle Θ with the point (16, −30) on its terminating side, what is the value of cosine?🔴 Answer: 1 🔴 on a question For an angle θ with the point (−5, −12) on its terminating side, what is the value of cosine? options: a. -5 b. -12 c. -5/13 d. -12/13 - the answers to brainsanswers.co.ukThe value of cosine is . Step-by-step explanation: It is given that an angle θ with the point (−20, −21) on its terminating side. It means the right angle triangle is formed in third quadrant where length of the perpendicular is 21 and the base is 20. According to the Pythagoras theorem, Taking square root both the sides. In a right angled

For an angle θ with the point (−5, −12) on its terminating

The point (-5,-12) is on the terminal side of an angle θ in standard position. Find the cosine value for this angle? I used pythagorean theorem to find the length of the hypotenese: a 2 + b 2 = c 2 (-5) 2 + (-12) 2 = c 2. 25 +144 = c 2. 169 1/2 = c 2. 13 = c. Then found the inverse of cosine to isloate the angle.The figure below shows an angle θ and its reference angle θ'. Because θ' is the reference angle of θ, both cos⁡(θ) and cos⁡(θ') have the same value. For example, 30° is the reference angle of 150°, and if we reference the unit circle, we can see that the cosines of both have a magnitude of , albeit they have different signs. BecauseGet an easy, free answer to your question in Top Homework Answers. For an angle θ with the point (16, −30) on its terminating side, what is the value of cosine? Get an easy, free answer to your question in Top Homework Answers.Find trig funtions values Call M (-15, 5sqrt7) the point od the terminal side terminal . Call m its projection on the x-axis. We have Om = - 15 and mn = 5sqrt7. The hypotenuse of the right triangle is: OM = sqrt(175 + 225) = 20 Call t the angle < mOM --> sin t = 5sqrt7/20 = sqrt7/4 cos t = - 15/20 = -3/4 tan t = sin/(cos) = (sqrt7/4)(- 4/3) = - sqrt7/3 cot = - 3/sqrt7 = - (3sqrt7)/7 sec t = 1Correct answer - For an angle (theta) with the point (5, -12) on its terminating side, what is the value of cosine? a) 5 b) -12 c) 5/13 d) -12/13
