Select two options. A point's location on the coordinate plane is indicated by an ordered pair, (x, y). A point has one dimension, length. A line has length and width. A distance along a line must have no beginning or end. A plane consists of an infinite set of points.A triangle has three sides and the sum of the angles of a triangle is 180 degrees. Triangles can be classified base on there angles and length of the sides. Therefore, let the length of the unknown angle = x. x + 65° + 57° = 180°. x + 122 = 180. subtract 122 from both sides. x + 122 - 122 = 180 - 122. x = 58 degrees.7) Find cot if cos 8) Find cos if sin 9) Find sec if cos 10) Find sin if sec 11) Find tan if csc 12) Find cos if sec Find the measure of each angle indicated.

In order to find the value of the interior angle of a regular polygon, the equation is (n −2)180∘ n where n is the number of sides of the regular polygon. Without more information, you can only find the value of the interior angles of a regular polygon. Using the equation is ( (n-2)180 ...Using Trigonometry to Find Angle Measures Date_____ Period____ Find each angle measure to the nearest degree. 1) tan A = 2.0503 64° 2) cos Z = 0.1219 83° 3) tan Y = 0.6494 33° 4) sin U = 0.8746 61° 5) cos V = 0.6820 47° 6) sin C = 0.2756 16° Find the measure of the indicated angle to the nearest degree. 7) 55 51? 68° 8) 19 27? 45° 9) 34 55 The formula for finding the total measure of all interior angles in a polygon is: (n - 2) x 180. In this case, n is the number of sides the polygon has. Some common polygon total angle measures are as follows: [2] The angles in a triangle (a 3-sided polygon) total 180 degrees. The angles in a quadrilateral (a 4-sided polygon) total 360 degrees.Its measure is equal to the sum of the two non-adjacent interior angle measures, thanks to the fact that all angle measures in a triangle add up to 180 degrees. Created by Sal Khan. ... Using the angle pair relationships of parallel lines, we would find that there are two pairs of alternate interior angles that are congruent to each other.Using Central Angles. There are two ways to determine the measure of inscribed angles. First, the measure of an inscribed angle is half the measure of the central angle with shared endpoints. The ...Geometry Name Triangle Review Part 1 Find the measure of the angle indicated. Find the measure of angle A. Part 2 Classifying Triangles Part 3 Triangle Congruence For the triangles below you can write ABC PQR. Corresponding Angles For each pair of triangles state the postulate or theorem that can be used to prove the triangles congruent. .
