Web8 apr. 2024 · If one angle is a 90 degrees, then all four angles 90 degrees: Since, the adjacent sides are supplementary. For example, ∠A, ∠B are adjacent angles and ∠A = 90°, then: ∠A + ∠B = 180° 90° + ∠B = 180° ∠B = 180° – 90° ∠B = 90° Similarly, ∠C = ∠D = 90° Example 1: In the adjoining figure, ∠D = 85° and ∠B = (x+25) °, find the value of x. WebThe formula for 180-degree rotation of a given value can be expressed as if R(x, y) is a point that needs to be rotated about the origin, then coordinates of this point after the rotation …
