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.

Three angles in a quadrilateral are 35 50 and 125 degrees what is the measure of the fourth angle?

35+50+125=210 all quads equal 360 degrees 360-210=150 x=150 degrees


What are the negative coterminal angles of 25 150 and 300?

To find negative coterminal angles, subtract 360 degrees from the given angles. For 25 degrees, the negative coterminal angle is (25 - 360 = -335) degrees. For 150 degrees, it is (150 - 360 = -210) degrees. For 300 degrees, the negative coterminal angle is (300 - 360 = -60) degrees.

What does 210 degrees look like?

Well, darling, 210 degrees is between 180 and 270 degrees on a standard protractor. So, picture a clock where the hour hand is pointing straight down towards 6, that's where 210 degrees would be. It's not rocket science, just a simple angle measurement.


What is the measure of the third exterior angle if Two exterior angles of a triangle have measures of 110 degrees and 100 degrees?

Exterior angle of any plane figure total 360 degrees, so 360 - (110 + 100) ie 360 - 210 = 150
