) Assume is in radians. The angles requested are measured counter-clockwise from the positive x-axis to the ray corresponding to the given point and are in [0,27]. The 4 right triangles depicted with one side on the x-axis all have horizontal sides of the same length. (a). (3 points) Let v = 4 cm. Fill-in the table below. Answers may include v, 0. Note: Each box is worth 1 point. y A: Coordinate: Angle: B: Coordinate: Angle: C: Coordinate: ( Angle: ) ) A B (b). (2 points) Write in terms of the other unknown quantity, h. 0=_ For parts (c)-(e) only, assume h = 7 cm. (c). (1 point) What is the radius, r? Be precise and show your work. 10 ---------- (h,v) C X (d). (1 point) Determine in radians. Show your work and, in the last step, use your calculator to evaluate to 2 decimal places. How do you know your answer is in radians and not degrees? (e). (1 point) Determine the angle, in radians, counter-clockwise from the positive x-axis (3 o'clock) to B. Write out all work by hand and in the last step you may use your calculator to evaluate the angle to 2 decimals. Is the angle you calculated in the correct quadrant? How do you know?
