Used when we know the lengths of any 2 sides of a right triangle and we need to know the third length. Formula: 𝑎 2 + 𝑏 2 = 𝑐 2 …where A and b are the legs and c is the hypotenuse. Trigonometry When we know only one side and one angle of a right triangle OR When ...
Answer to: Suppose that theta is an acute angle of a right triangle and that sec(theta) = 12/7. Find sin(theta) and cot(theta). By signing up,...
The arctangent or also called the inverse tangent is basically the inverse of the basic trigonometric tangent function whereas it reverses the process by which it determines an acute angle of a right triangle with respect to the length of the given opposite side and the adja...
So theta = arcsin(3/5) = arccos(4/5) = arctan(3/4) = 36.87°. This allows us to calculate the other non-right angle as well, because this must be 180-90-36.87 = 53.13°. This is because the sum of all angles of a triangle always is 180°. We can check this using the sin...

The Cos Theta Formula is especially useful when working with right-angled triangles. In a right triangle, the Cosine of an angle will always be the length of the adjacent side divided by the length of the hypotenuse. This makes it a great tool for solving problems involving Cosine. The impo...
What is the area of a right isosceles triangle with a hypotenuse of length 10 inches? Find the angle that maximizes the area of the isosceles triangle whose legs have length b=c=31 . Two sides of the triangle have length a and b, and the angle between them is theta. What value...
What is the largest rectangle that can be circumscribed around a rectangle of sides L and H? (Hint: express the area of the circumscribed rectangle in terms of the angle \Theta. See figure below.) A rectangle is inscribed in an isosceles rig...

We study the $$J/\psi \rightarrow K^+ K^- f_0(980)(a_0(980))$$ reaction and find that the mechanism to produce this decay develops a triangle singularity a
