Webb10 juli 2016 · I am confused about the Unit Circle explanation for the trigonometric ratios for angles greater than 90 degrees. It seems that for the first (top right) quadrant, sin ( θ) is equivalent to the y-coordinate, because sin ( θ) = opposite / hypotenuse sin ( θ) = opposite [hypotenuse is 1] sin WebbA: The angles are given below;- Q: If s denotes the length of the arc of a circle of radius r subtended by a central angle 0, find the… A: We will find the value of length of an arc of circle. Q: Circles B and E have radii of 10 cm & 7 cm respectively, and CD is 3 cm. Use this information to…
