3.5
3.5(180/pi) = 200.53 degrees
200.53 - 180 = 20.53
20.53(pi/180) = 0.3584
The reference angle for an angle with the measure of 175 degrees is 5 degrees
Quadrantals are their own reference angle, so 90 degrees.
An acute angle
in order to find the reference angle, an angle less than or equal to 90 degrees formed by the x-axis and the terminal side of an angle, one needs to first find what quadrant on the coordinate plane the angle belongs to. The negative (-) sign in -140 refers to the direction 360 degree turn begins at (and therefore the quadrant it begins at). Instead of taking the regular backwards "C", counterclockwise direction, the turn begins clockwise. To convert it, simply add 360 degrees, to get 220 degrees, an angle in the third quadrant. These are the guidelines to follow when finding reference angles: If angle, A, is in first quadrant then the reference angle will be itself as it is already 90 degrees or under. If angle, A, is in second quadrant then the reference angle will be 180 - A . If angle, A, is in third quadrant then the reference angle will be A - 180 . If angle, A, is in fourth quadrant then the reference angle will be 360 - A " These subtractions are all in reference to the nearest angle of a quadrant and are in degrees. Being in the third quadrant, take the angle, A, and subtract 180 from it to get: 220 - 180 = 40 Thus, the reference angle for -140 degrees is 40 degrees. Follow the same directions for other angles, first determining whether the angle needs to be converted into a positive value (counterclockwise), then locate the quadrant and use the rules above for the specific angle(s) being looked at and asked for.
yes, an acute angle is any angle under 90 degrees.
35 degrees
The reference angle for 325 degrees is 35 degrees which is found by subtracting 325 from 360 since it is in the third quadrant.
The reference angle for an angle with the measure of 175 degrees is 5 degrees
35 degree angle is acute.
A main angle of refrence.
360-331=2929 degrees is your reference angle. Remember your signs, though.
The angle of reference is in the first quadrant, and 90 degrees angle is not in the quadrant.
When using a protractor, 35 degrees would be measured by aligning the baseline of the protractor with the starting point and then marking the 35-degree angle from there. It would look like an angle that is less than 45 degrees but greater than 30 degrees, as a reference point.
The supplement of a 35 degree angle would be 145 degree angle.
The supplement of a 35 degree angle would be 145 degree angle.
Quadrantals are their own reference angle, so 90 degrees.
The supplementary angle to a 145 degree angle will be a 35 degree angle because 145 + 35 = 180.
