Mole ratios are the coefficients of the what?
Mole ratios are the coefficients of the balanced chemical equation. They represent the relative amounts of reactants and products involved in a chemical reaction. These ratios allow chemists to calculate the amounts of substances consumed or produced during the reaction. Understanding mole ratios is essential for stoichiometric calculations in chemistry.
If measures of 3 supplementary angles are in the ratio 1 to 3 to 2 what are the values of the angles?
call the small angle x, then given the ratios we have x+2x+3x=180 6x=180 so x=30 The angles are 30, 60, and 90.
What are the 3 trig ratios and how do they work?
A right angle triangle has three sides and three interior angles one of which is 90 degrees. The names of its sides are the adjacent the opposite and the hypotenuse and using the 3 trig ratios we can find the interior angles or lengths of the sides depending on the information given.Tangent angle = opposite/adjacentSine angle = opposite/hypotenuseCosine angle = adjacent/hypotenuseIf we are given the lengths of 2 sides we can work out the angles with the above ratios.If we are given a length and an angle we can work out the lengths of the other 2 sides by rearranging the above ratios.
How can you find the angles of a right triangle with sides 20 21 and 29?
Because it's a right angle triangle use any of the trigonometrical ratios to find the two interior acute angles: tangent = opp/adj, sine = opp/hyp and cosine = adj/hyp The angles are to the nearest degree 46 and 44
When two ratios are equal what are they called?
They are called equivalent ratios.
Why do similar triangles have the same trigonometric ratios?
Trigonometric ratios are characteristics of angles, not of lengths. And, by definition, the corresponding angles an similar triangles have the same measures.
What complements tan 132 degree angle?
Complements are defined for angles, not trigonometric ratios of angles.
Does a rectangular prism have any secants?
Yes, since it has vertices it has angles and since it has angles it has trigonometric ratios
How many trigonometric ratios are there?
Six.
What does trigonometric identities all about?
They are true statements about trigonometric ratios and their relationships irrespective of the value of the angle.
What are the connections between right triangle ratios trigonometric functions and the unit circle?
Right triangle ratios serve as the foundation for defining trigonometric functions such as sine, cosine, and tangent, which relate the angles of a triangle to the lengths of its sides. The unit circle, a circle with a radius of one centered at the origin of a coordinate plane, extends these concepts by allowing trigonometric functions to be defined for all angles, not just those in right triangles. In the unit circle, the x-coordinate corresponds to the cosine of the angle, while the y-coordinate corresponds to the sine, thus linking the geometric representation of angles to their trigonometric values. This connection facilitates the understanding of periodic properties and the behavior of trigonometric functions across all quadrants.
How do you find trigonometric ratios of angles greater than 90 degrees?
subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
What is the difference between a tangent and a secant?
They are different trigonometric ratios!
