What is the measure of ∠Y? 43° 68° 86° 172°

Solution:Here we are given the arc xz=86.we have been asked to find the measure of angle Y.As we know that the Inscribed angle is Half of the measure of the intercepted arc.Here intercepted arc=86So we can write [tex] <y=\frac{1}{2}*86\\
\\
<y=43\\ [/tex]Hence the value of the angle y is 43 degrees.
