Answer and Explanation: Anne : If you have a regular polygon all the sides and angles are congruent; you can use the formula n=360/180-A, where n is the number of sides and A is the degree of the angle.Insert context header here:Insert context explanation here......
Introduction to Value of sin 15 The sine of 15 degrees, abbreviated sin 15°, is a trigonometric function that expresses the ratio of the length of a right triangle’s side opposite a 15-degree angle to the length of the hypotenuse. It is an irrational number that is roughly equivalent ...
The derivative comes up in a lot of mathematical problems. An example is finding the tangent line to a function in a specific point. To get the slope of this line, you will need the derivative to find the slope of the function in that point. Math: How to Find the Tangent Line of a...
How to Find Exact Values of Sine & Cosecant Using the Unit Circle & Special Triangles: Example with Sine Evaluate the expressionsin225∘. Give an exact answer. Step 1:225∘is in quadrant III since180∘<225∘<270∘. Therefore,sin225∘is negative. ...
Step 1: We will need to use the inverse cosine function on −79 to get θ. Step 2: Input cos−1(−79) into your calculator; the result is cos−1(79)=141.06∘ to the nearest hundredth of a degree. This is in quadrant II. How to Find Inverses of Sine, Cosi...
5. Find The New Sine Take the value of the other known side and divide it by X. This new number equals the sine of the new angle. 6. Solve For The Angle Enter the number in the calculator and hit the "sin-1" to get the angle in degrees. You can now solve for the ang...
