Therefore, the degrees of a reflex angle can be easily calculated. For example, if an acute angle measures 56°, then its corresponding reflex angle will be 360° - 56° = 304°. Similarly, if an obtuse angle measures 97°, then its corresponding reflex angle will be 360° - 97° = 263°.

WebSep 15, 2024 · Theorem 2.5. For any triangle ABC, the radius R of its circumscribed circle is given by: 2R = a sinA = b sin B = c sin C. Note: For a circle of diameter 1, this means a = sin A, b = sinB, and c = sinC .) To prove this, let O be the center of the circumscribed circle for a triangle ABC. WebExample 1. Find the measure of the missing angles x and y in the diagram below. Solution. x = 80 o (the exterior angle = the opposite interior angle). y + 70 o = 180 o (opposite angles are supplementary). Subtract 70 o on both sides. y = 110 o. Therefore, the measure of angles x and y are 80 o and 110 o, respectively.
