How do you find an angle of a right triangle?
you need to have at least 2 values of the lengths of the triangle and then you can find the angle by sine, cosine or tangent formulas you may try this online calculator for right triangles. http://www.rillocenter.com/calculate/trigonometry.html
When finding the sides and angles of a right triangle when is it necessary to use Trigonometry?
if you have any two sides, you can calculate either of the (non right angle) angles. if you have a (non right angle) angle and one side, you can calculate any other side. you will need either tables, or a scientific calculator with sin / cosine / tangent function
Is a traingle is regular or not regular?
Only when its an equilateral triangle then it is a regular polygon
What is the difference in algebra and calculus and trig?
Algebra is basically arithmetic with variable expressions, trigonometry comes after algebra because you need algebra to understand sine, cosine, tangent, as well as secant, cosecant, and cotangent.
How do you find the pirimeter of a traingle?
Assuming you mean perimeter (not pirimeter) and triangle (traingle) you need to sum together the lengths of the three sides.

Is a traingle a regular polygon or a polygon?
A triangle (not traingle) is a polygon. It can be a regular polygon but need not be.

How do you find angles on a right triangle?
You do not need to, if you have a right triangle that angle is 90* so the other 2 angles are 45* apiece. That is actually only partially accurate. There can be a right angled triangle with sides of 2-3-5. 5 being the hypotenuse in which the triangle's angles will not be 90-45-45 but 90-33.69-56.31. To find the angles of a right triangle, you will need to know the length of the sides. With the length of all three sides, you will need to utilize sine, cosine, and tangent to find the angles.
Which two trigonometric functions are used for analyzing vectors?
You usually need all three primary functions. The sine and cosine functions are used to resolve the vector along orthogonal axes, and the tangent function is used to find its direction.
Why dont you have buttons for cotangent secant cosecant?
You don't have buttons for cotangent, secant, and cosecant because you don't need them. Just invert. Cotangent is 1 over tangent, secant is 1 over sine, and cosecant is 1 over cosine.
A brace for a shelf has the shape of a right traingle its hypotenuse is 10 inches long and the wo legs are equal in length how long are the legs of the traingle .need the formula please?
The only formula you need is one that we're sure you already know.In every right triangle,(leg-A)2 + (leg-B)2 = (hypotenuse)2In this right triangle, the legs are equal, and the hypotenuse is 10.(leg)2 + (leg)2 = (10)22 times (leg)2 = 100Can you take it from there ?
How do you find the equation of a parabola if you know the equation of the tangent that touches it?
You need more than one tangent to find the equation of a parabola.
How do you find the angles of a triangle that is not a right triangle if you only have the side measurements?
If it's not a right angled triangle and you don't have any of the angles but have the values of all three sides, then you need to use something called the Cosine Rule.
