"WebExample 2: Find the missing angle x° using the intersecting secants theorem of a circle, given arc QS = 75° and arc PR= x°. Solution: Using the secant of a circle formula (intersecting secants theorem), we know that the angle formed between 2 secants = (1/2) (major arc + minor arc) 45° = 1/2 (75° + x°) 75° + x° = 90°.
