Do not use decimals. a. What is the reference angle? b. In what quadrant is this angle? sin(330° ) = _____ cos(330° ) = _____When the terminal side is in the fourth quadrant (angles from 270° to 360°), our reference angle is 360° minus our given angle. So, if our given angle is 332°, then its reference angle is 360° – 332° = 28°.This 60° angle, shown in red, is the reference angle for 300°. The terminal side of the 90° angle and the x-axis form a 90° angle. The reference angle is the same as the original angle in this case. In fact, any angle from 0° to 90° is the same as its reference angle.Roof Pitch Angle and Slope Factor Charts. Roof Pitch is a term describing how steep or flat your roof slope is.

Well, the reference angle is the angle [the one which is the smallest] ... How do you express as a trigonometric function of an angle in quadrant 1 given sec(330)?The grade would be 0.06. To calculate the grade of a road with: rise = 12 m; and. run = 200 m: Compute the ratio between rise and run: grade = rise/run = 12/200 = 0.06. If you want to know the angle of the slope, input the value in the arctangent function: slope (angle) = arctan (rise/run) = arctan (12/200) = 3.43°.Our cotangent calculator accepts input in degrees or radians, so once you have your angle measurement, just type it in and press "calculate". Alternatively, if the angle is unknown, but the lengths of the two sides of a right angle triangle are known, calculating the cotangent is just a matter of dividing the adjacent by the opposite side. For ...360 - 330 = 30, so we are subtracting 30 degrees from 360 to get the sin inverse, 330. Since we are subtracting from 360, the ratio will remain sin, and because it is in the 4th quadrant, the sin will be negative. Therefore, our answer is −sin(30), or − 1 2. Sorry if this seems confusing, this is how I learnt it. Answer link.
