The angle of reference is in the first quadrant, and 90 degrees angle is not in the quadrant.

Why is ninety degree not taken as the angle of reference?
in trig a reference angle is ised to create a reference triangle in the first quadrant by using any point except the origin that lies on the terminal side of the ref. angle and drawing a perpendicular to the x-axis. for 90 degrees the terminal side is the y-axis and the perpendicular would not create a triangle, but just retrace the y-axis.
What is after trigonometry?
Generally pre-calculus is taken after trigonometry, unless the trigonometry course was supplemented by a pre-calculus course, in which case the next course would be calculus.
Why is degrees not taken as the angle of reference in trignometry?
They often are. Sometimes, however, radians are used for the measures of angles and for labeling graphs. This is because later aspects of trigonometry, like polar coordinates, arc lengths, and wave graphs, are more easily explored with radians. Pi commonly appears and is more easily understood as π than as 3.14159.... Circles, with areas of πr^2, are frequent and periods of wave function are almost always expressed in radians. Radians become as useful and widespread as degrees.
Can calculus and trigonometry be taken in the same semester in collge?
It depends on the college and since you have not bothered to specify which one, I cannot provide a more useful answer.
Why angle is taken as double in mohr's circle?
because this is called science...
Why is 90 degrees taken as angle of reference in trigonometry?
It is not. The angle of reference is 2*pi radians or 360 degrees.

Is trigonometry before pre-calculus?
They can be taken at the same time.
What year of high school is trigonometry usually taken?
there is an introat the end of grade ten but there is a real unit in grade eleven trigonometry is usaully taken during geometry and parts of pre/calculus. Its about 10th and/or 11th grade!
How long is a pitching mound to first base?
64 feet.....shoulda taken trigonometry!
Why is 90 degrees not taken as the angle of reference?
If I understand the question correctly, the answer is that it is simply a case of convention. For bearings, for example, the reference line is North and angles are measured clockwise. In 2-D polar coordinates, the reference line is the horizontal (going East) and angles are measured in the anti-clockwise direction.
How do you find the dimensions of a flat surface?
If the surface is small enough, the length of each edge can be taken using a ruler or tape measure. If the surface is too large, say, the side of a building, you can use trigonometry. eg: for a building, take a point a known distance from the building's base and measure the angle from that point to the top. the building's height istan(angle) x distance from base

What is the measure of the largest angle in an obtuse triangle?
178 degrees is the largest angle for an obtuse angle because 180 is a straight angle and 90 degrees is an right angle and below 90 degrees is an acute angle. Some supposedly say that the answer is 179,But it's not! the reason behind this is because in a triangle all the angles have to add up to 180 degrees. There are 3 points to a triangle so there has to be 2 extra degrees taken off of 180, which equals to 178. Explanation is terms: angle A + angle B + angle C = 180 degrees [Sum of supplementary angles of a triangle] 178 degrees + 1 degree + 1 degree = 180 degrees which makes sense. I figured this out when i was doing homework... Hope this helps you other people
