How do you find the measurement of the angles in a polygon? Can a scalene triangle be a right angle triangle? How to find the number of sides of a polygon using the given angle? Find the measure of angle A if angle A is complementary to angle B, angle B is supplementary to angle ...
Obtain the proper information to make the calculation. Sketch the right triangle and label the sides — opposite, adjacent and hypotenuse — in metric units. Insert the angles in degrees if the question contains that information, or use variable (theta) to label an unknown angle. Write the val...

In the triangle above we are going to calculate the angle theta. Let x = 3, y = 4. Then by the Pythagorean theorem we know that r = 5, since sqrt(32+ 42) = 5. Now we can calculate the angle theta in three different ways. sin(theta) = y/r = 3/5 cos(theta) = x/r = ...
A triangle is a three-sided polygon. Instructors often ask intermediate and advanced-level math students to calculate the missing angle in a triangle. One method of finding a missing angle is based on the premise that the sum of the interior angles of a
How to Find Trigonometric Ratios Given a Right Triangle: Example 1 Given the right triangle depicted below, calculate all six of the trigonometric ratios of {eq}\theta {/eq}. Step 1: Identify the sides of the right triangle and their lengths. ...
How to find {eq}x = tanx? {/eq} Trigonometry Function:The trigonometry function tangent is used on an angle. In a right-angled triangle, the tangent of an angle is {eq}\tan(\theta)=\frac{p}{b} {/eq}, where {eq}p {/eq} is the length of the side opposite to the angle {eq...
Plz check this and correct this one to find the centroid of the sectored circle.: x=[3]; y=[3]; r=[2]; delta=pi/2; theta=2*pi; theta2 = theta + delta/2; t = linspace(theta,theta2); A = x + r*cos(t); B = y + r*sin(t...
The trigonometric functions relate an angle expressed in radians or degrees to two out of three sides in a right triangle. What is the angle θ? The Greek letter theta (θ) is commonly used to represent an unknown angle in a right triangle. What is a right triangle? A right triangle is...
Prove or disprove: For all x in the quaternions \mathbb{H}, \left( {x + i} \right) \cdot \left( {x - i} \right) = {x^2} + 1. Prove that \frac{sin \theta}{cos \theta} + \frac{cos \theta}{sin \theta} = csc \theta.sec\...
