Y=AB⌢2 Where Y is the angle formed by the two chords, and AB is the arc formed by the two chords. Answer and Explanation: We are given a circle. Our objective is to find each measure with the inscribed angle. A) m∠DEF The angle DEF is an.....
Since the inscribed angle subtends the arc {eq}\widehat{CB} {/eq} (whose measure is equal to the {eq}m\angle{CAB} {/eq}), we would take half of {eq}m\angle{CAB} {/eq} to find the measure of the inscribed angle. If {eq}m\angle{CAB}=80^{\circ} {/eq}, then {eq...
