	Degrees, minutes and seconds		2020-02-21
		Jonathan pose la question : If a cone has an angle of 22 degrees, when i place it flat on a surface, the new resulting central angle is now at 68.69123834, but how come when i saw it on my friend it say 68 degree and 40 minutes, what is this minute? Penny Nom lui répond.
	Do all angles have to be equal to a number?		2019-05-15
		Malik pose la question : Do all angles have to be equal to a number? By all angles I mean adjacent, vertical, supplementary, complementary. Penny Nom lui répond.

		pavidthra pose la question : Length or arc 11 and angle of subtended 45.need to find a radius Penny Nom lui répond.
	cos(x) = -1/(square root of 2)		2011-04-27
		Shelby pose la question : Find exact value of x for 1 <(or equal to) x < 2pi a) cos(x) = -1/(square root of 2) Penny Nom lui répond.
	sin x = -0.25		2011-03-29
		Wayne pose la question : How do you solve for x in the equation sin x = -0.25 the answer is 3.394 and 6.030 but I don't know the steps they used to calculate this Penny Nom lui répond.
	The maximum number of right angles in a polygon		2009-10-05
		Bruce pose la question : Is there way other than by trial and error drawing to determine the maximum number of right angles in a polygon? Secondary question would be maximum number of right angles in a CONVEX polygon. Is there a mathematical way to look at this for both convex and concave polygons? Or are we limited to trial and error drawing? Chris Fisher lui répond.
	Is 360 Really the correct value?		2005-08-15
		Jack pose la question : Considering the circumference of a "Perfect Circle" with a Diameter of 1 meter would be something like 3.14 meters, why do we use the number 360 to represent the number of degrees within that circumference? Would it not make more sense to express the degrees in reference to the relationship to the diameter as related to pi? That is, let's just say our "Perfect Circle" has a circumference of 3.14 meters, therefore, what we now consider as due east would change from 90 Degrees to 78.5 Degrees. Penny Nom lui répond.
	The tangent of theta		2004-07-10
		Jacob pose la question : P is a point on a unit circle with coordinates(0.6,0.8). Find tan of theta. My book shows me how to do it,"tan of theta=opp./adj.=0.8/0.6=4/3,"and leaves it as that's the answer(4/3).When do we know from a problem to find the angle measure (in this case, the angle measure of theta) and how do we know when to give something like 4/3 without converting it to the angle measure? Penny Nom lui répond.
