- To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360° if the angle is measured in degrees or 2π if the angle is measured in radians. Example 1: Find a positive and a negative angle coterminal with a 55° angle. 55° – 360° = –305°.55° + 360° = 415°.A –305° angle and a 415° angle are coterminal with a 55° angle.

- Find the smallest positive coterminal angle for an angle measuring -400 degrees. Since the angle is negative, we know that the terminal side spun clockwise. One clockwise rotation would have been -360 degrees, so at -400 degrees we have gone past one complete rotation.

- So if you need to solve for the vertex angle $\theta$, we have that $\theta = 180 - 2x$. Also note, to find an angle, given none of the angles are known, you can to use the lengths of the sides of the triangle to solve for the base angles and/or vertex, and can use the Law of Cosines to do that. share | cite | improve this answer.

- All you have to know is that all of the angles in a triangle always add up to 180°. This is true 100% of the time. So, if you know two of the three measurements of the triangle, then you're only missing one piece of the puzzle. The first thing you can do is add up the angle measurements you know. In this example, the two angle measurements you know are 80° and 65°. Add them up (80° + 65°) to get 145°.

- Every circle has 360 degrees. Each of the central angles for your food choices can be found by calculating that percentage of the circle. For example, if the central angle was 5%, then the angle would be 5% of 360 degrees, or 0.05 x 360 = 18 degrees.

- In the figure, assume the measure of Angle A = x. When two adjacent angles form a straight line, they are supplementary. Therefore, the measure of Angle C = 180 − x. Similarly, the measure of Angle D = 180 − x.n many contexts, an angle of − θ is effectively equivalent to an angle of one full turn minus θ . For example, an orientation represented as −45° is effectively equivalent to an orientation represented as 360° − 45° or 315°. However, a rotation of −45° would not be the same as a rotation of 315°.

How to Calculate the Arc Length, Central Angle, and Circumference of a Circle Calculating Arc Length. Calculate the circle's circumference. Calculate the central angle of your circle, using the protractor, then represent this angle as a fraction. As there are 360 degrees in all circles, make 360 the denominator of the fraction. The angle measurement is the numerator. Divide the numerator by the denominator to place the number in decimal form. Multiply the circumference by the decimal to learn the arc length of that section of the circle.
