What is the tangent of a right triangle?
There is no such thing as the tangent of a triangle. Circles, angles, and conversations have tangents. In a right angled triangle, the tangent of one of the acute angles is the ratio of the length of the side opposite the angle to the length of the side adjacent to it.
What does X equal for the equation negative sin x minus cos x equals 0?
Consider the meaning of the sine and cosine functions. They are ratios of the side lengths in a right triangle. Sine is the length of the side opposite the angle, divided by that of the hypotenuse, and cosine is the length of the adjacent side, again, divided by the length of the hypotenuse. Consider then: sin = o/h cos = a/h This means that according to our problem, if x is the angle we're measuring in the triangle: -(o / h) - (a / h) = 0 ∴ -o - a = 0 ∴ a = -o Which tells us that the opposite and adjacent sides on our triangle are of equal length. This means that our triangle is not only a right triangle, but an isosceles triangle as well. That means that our angle (x) must be π/4, or 45°
How do you find the width and length of a rectangle knowing ONLY the diagonal and its angle?
By using the trigonometric ratios of Sine and Cosine. The diagonal forms the hypotenuse of a right angled triangle with the length and width of the rectangle forming the other two sides of the triangle - the adjacent and opposite sides to the angle. Then: sine = opposite/hypotenuse → opposite = hypotenuse x sine(angle) cosine = adjacent/hypotenuse → adjacent = hypotenuse x cosine(angle)
What is the relationship among a right triangle?
There is the Pythagorean relationship between the side lengths. Given a right triangle with sides a, b, & c : Sides a & b are adjacent to the right angle, and side c is opposite the right angle, and this side is called the hypotenuse. Side c is always the longest side, and can be found by c2 = a2 + b2 The 2 angles (which are not the right angle) will add up to 90° Given one of those angles (call it A), then sin(A) = (opposite)/(hypotenuse) {which is the length of the side opposite of angle A, divided by the length of the hypotenuse} cos(A) = (adjacent)/(hypotenuse), and tan(A) = (opposite)/(adjacent).
When you say Tangent of 30 equals -6.40 what does the -6.40 represent. Is it the length of something or the angle of something?
-6.40 It is the length of the opposite leg divided by the length of the adjacent leg
What is the definition of secant-tangent angle?
The secant of an angle in a right triangle is the hypotenuse divided by the adjacent side. The tangent angle of a right triangle is the length of the opposite side divided by the length of the adjacent side.
If you divide length of the opposite side of an angle in a right triangle by the length of the adjacent side what value do you get?
It is a tangent.
How do you find the angle adjacent to the hypotenuse?
Remember SOHCAHTOA which means, the Sin of an angle is equal to the Opposite side divided by the Hypotenuse, the Cos of an angle is equal to the Adjacent side divided by the hypotenuse, and the Tangent of an angle is equal to the Opposite side divided by the Adjacent side. So as long as you have two sides of a right triangle, then you can find the angles and the length of the third side.
What are the different function?
In a right triangle,the sine (sin) of one of the acute angles is the length of the opposite side divided by the length of the hypotenuse.the cosine (cos) is the length of the adjacent side divided by the length of the hypotenuse.the tangent (tan) is the length of the opposite side divided by the length of the adjacent side.The three others, cotangent, secant and cosecant, are merely reciprocals of the first three.The inverse functions, arcsine, arccosine, and arctangent respectively, each takes as an input the ratio of two sides and outputs an angle.

Is the ratio of the length of the opposite leg to the length of the adjacent leg?
Suppose ABC is a triangle. There is nothing in the question that requires the triangle to be right angled. Suppose AB is the side opposite to angle C and BC is a side adjacent to angle C. Then AB/BC = sin(C)/sin(A)
How do you calculate tangent of an angle?
the tangent of an angle is equal to the length of the opposite side from the angle divided by the length of the side adjacent to the angle.
What is sine cosine and tangent?
In a right triangle, the sine of one of the angles other than the right angle is the length of the side opposite the angle divided by the length of the hypotenuse (the side opposite the right angle), the cosine is the length of the side adjacent to the angle divided by the length of the hypotenuse, and the tangent is the length of the opposite side divided by the length of the adjacent side.
