A quadrantal angle is one that in 0 degrees, 90 degrees, 180 degrees, 270 degrees or 360 degrees (the last one being the same as 0 degrees). These are the angles formed by the coordinate axes with the positive direction of the x-axis. All other angles (in the range 0 to 360 degrees) are non-quadrantal

Find value of trigonometric functions of quadrantal angle?
sin 0=13/85
What is tan on a scientific calculator?
It is a trigonometric equation for a right triangle, to find a non-right-angle angle. Using SOHCAHTOA, it is the opposite side divided by the adjacent angle
What ratio correctly describes the sine function?
In a right triangle, the sine of an (non right angle) angle would the ratio of the opposite side (opposite to the angle selected) and the hypotenuse
What is a non example of a congruent angle?
Well, honey, a non-example of a congruent angle would be two angles that are different in measure and don't have the same degree of sass. So, if you have one angle throwing shade at 30 degrees and another angle serving looks at 45 degrees, those two are definitely not congruent. Just like mixing stripes with polka dots, it's a fashion faux pas in the world of geometry.
what- Fill in blank 1 and blank 2 to explain why Angle-Side-Angle Congruence helps imply Angle-Angle-Side Congruence?
(1) third angle, (2) included
What is the angle when the terminal side of an angle in standard position lies along one of the axes?
Quadrantal angle
Is 38 pi divided by 4 radians a quadrantal angle?
9.5
Can you find the reference angle of a quadrantal angle?
Yes. Quadrantal angles have reference angles of either 0 degrees (e.g. 0 degrees and 180 degrees) or 90 degrees (e.g. 90 degrees and 270 degrees).

What is the measure of quadrantal angle?
A quadrantal angle is one whose initial arm is the positive x-axis and whose terminal arm is on the y-axis or the y-axis.In other words, it is k(90 degrees), k is an integer.(in radians: k(pi)/2)
What is quadrantal angle?
A Quadrantal angle is an angle that is not in Quadrant I. Consider angle 120. You want to find cos(120) . 120 lies in quadrant II. Also, 120=180-60. So, it is enough to find cos(60) and put the proper sign. cos(60)=1/2. Cosine is negative in quadrant II, Therefore, cos(120) = -1/2.
