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
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.
Yes, congruent angles are angles that have the same measure.
solutions of the equation: x2-x=20
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 with the same angle measure are congruent.
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.

what is the equation to figure the angles of a polygon?
Yes, congruent angles are angles that have the same measure.
solutions of the equation: x2-x=20
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.

A rhombus has 2 equal opposite acute angles and 2 equal opposite obtuse angles whereas the 4 interior angles add up to 360 degrees
The unit of measure used to determine an absolute location on a map or a globe is a degree. This is a unit of measurement for angles used in geography and cartography.
The three interior angles measure 45, 45 and 90 degrees.
