x = 3(180 - x) - 4 ie x = 540 - 3x - 4 ie 4x = 536 so x = 134 deg Check: 46 x 3 = 138; 138 - 4 = 134. QED

How do you find the size of an angle without using a protractor?

If the angle is a lone, random angle, I believe you would need a protractor to determine the precise size of the angle (in "degrees"). However, you could, in this case, roughly guess as to whether the angle is acute, obtuse, or right (if the little rectangle is shown in the angle). Of course, if an angle is in a position where one can determine its measure using known postulates or theorems, finding the size of this angle becomes much easier. For example, if you know the measure of one angle and you must determine the measure of another angle, but these two angles are vertical angles, or are corresponding angles (by the corresponding angles postulate), you can indeed determine the measure of this angle without a protractor. Additionally, another example is that if you knew a pair of angles were either supplementary angles, complementary angles, or a linear pair, and you were given the measure of one of these angles, you could determine the measure of the other angle without a protractor. Therefore, it depends on the angle you're looking at.


Are congruent angles angles that have measure?

Yes, congruent angles are angles that have the same measure.


What is another way to describe two angles that each measure 76 is to say they are?

solutions of the equation: x2-x=20


How do you use angle relationship to determine a missing angle measurement?

The answer depends on the context. Angles are related in many ways: parallel lines, angles at a point, angles in a polygon - all impose constraints on angles from which their measure may be determined.


Angles that have the same measure are?

Angles with the same angle measure are congruent.

How can one determine the miter angles for a project?

To determine the miter angles for a project, you can use a miter saw or a protractor to measure and cut the angles needed for the corners of your project. Make sure to accurately measure and mark the angles before cutting to ensure precise and clean cuts.


Measure of angles on 17 sided polygon?

That depends what you are talking about. The interior angles equation is: Degrees=180(n-2) when n is the number of sides. The exterior angles are always 360. In this question, the measure of the interior angles would be 2700 degrees.

In this parallelogram the measure of angle b is twice the measure of angle a What is the measure of angle a?

The adjacent angles of a parallelogram are supplementary. This means that angle A + angle B = 180 deg.Since angle B = 2*angle A, then angle A + 2*angle A = 180 deg ie 3*angle A = 180 deg so that angle A = 60 deg.
