Best Answer

You could

measure it using a protractor,

derive it from basic geometric properties (for example angles of a regular polygon), or

calculate it using trigonometry.

If it is a scalene triangle then: 180 - the sum of the 2 known angles = x angle

Angle a, by itself has no value. You must first assign a value to a to get the value of tan a.

You measure it. An interior angle of an ordinary polygon can have any value in the range (0, 360) degrees excluding 180 degrees. There is no constraint on the size of a single angle.

The inverse cos of 1 is equal to o degrees. You can find this answer by knowing what angle measurement has cos equal to a value of 1.

A trapezoid should add up to 360 degrees. add the angles that are shown and subtract by 360. the missing angle should be found.

A side of the triangle below has been extended to form an exterior angle of 133°. Find the value of x

If these two sides are opposite to these angles, and you know one of the angles, you can use the Law of Sines to find the other angle. For example, in the triangle ABC the side a is opposite to the angle A, and the side b is opposite to the angle B. If you know the lengths of these sides, a and b, and you know the measure of the angle B, then sin A/a = sin B/b multiply by a to both sides; sin A = asin B Use your calculator to find the value of arcsin(value of asin b), which is the measure of the angle A. So, Press 2ND, sin, value of asin B, ).

It depends on what value you require: th length of a side, a measure of an angle, the area. And it also depends on what information you do have.
