Why is 90 degree not taken as the angle of reference in trigonometry?
The angle of reference is in the first quadrant, and 90 degrees angle is not in the quadrant.
What is the reference angle for an angle with a measure of 175 degree?
5 degrees
What is the reference angle for an angle with a measure of 331 degree?
29 degrees
What is angle of reference in trigonometry?
This is a VERY important question and I am glad you asked it. First you have to remember that in drawing angles we think of 4 quadrants. Think of the XY plane - the first quadrant is where BOTH X and Y are positive. In the 2nd quadrant the X is negative and the Y is positive. In the 3rd quadrant the X and the Y are negative. In the 4th quadrant the X is positive and the Y is negative. Normally when we draw an angle we draw an angle less than 90 degrees. However, we can draw any angle we want from 0 to 360. However that angle can be represented by an angle less than 90 degrees in a certain quadrant. Take an angle like 120 degrees. That angle is the same as a 60 degree angle in the 2nd quadrant. A 210 degree angle is the same as a 30 degree angle in the 3rd quadrant. A 359 degree angle is the same as a 1 degree angle in the 4th quadrant. Those smaller angles are reference angles. This explanation would be better if I could insert graphs. I have attached a link to a picture. Alpha is the angle and Beta is the reference angle.
How do you draw an angle that measures 243 degrees?
you can only draw an reflex angle if you have a circular protractorthere is also a way with a normal protractor you can rotate your protractor and there you can now make ur Reflex angleRememberyou should minus 1 degree
What is the reference angle to a 140 degree angle?
60

5 degrees
What is the reference angle for an angle with a measure of 331 degree?
29 degrees
What is the reference angle for 30 degrees?
A 30 degree angle is an acute angle because it is greater than 0 but less than 90 degrees.
What is the reference angle of -370 degree?
A reference angle is the positive angle less than 360 which is coterminal with the given angle. For a negative angle add 360 repeatedly until you gat an answer less than 360. =370 + 360 = -10 -10 +360 = 350
What is the reference angle for 17 degree?
17 degrees is an acute angle because it's greater than 0 but less than 90 degrees.
How do you draw an angle of 55 degree with compass and pencil?
you will have to construct a 135 degree angle first...but constructing a 90 degree with a 45 degree to give u the 135 degree angle and then using that as a reference, u will have to draw a 60 degree angle going counter clockwise from the 135 degree angle so that 135-60=55 degree...hahah I know it is confusing but if only i could show you...cz i mean visual is better than oral right !??! haha ^D^... hope i can help....
