How to solve reference angles

WebMar 3, 2024 · 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. WebAug 18, 2024 · Solution: The two angles are a linear pair (from a straight line), So they must add to [Math Processing Error] = 180 ∘. Write an equation based on what you know: [Math Processing Error] x + 42 = 180. Solve the equation: [Math Processing Error] x + 42 = 180 → x = 180 − 42 → x = 138. The missing angle is [Math Processing Error] x = 138 ∘.
