Given that , and , find , and .
In the figure, both and are subtended
by . Since the measures of inscribed angles
subtended by the same arc are equal, . This means that the value of is . Use
the fact that the sum of the measures of the interior angles of a
triangle is , along with the fact that the measure of is the same as the measure of , to find the value of as follows:
Both and are subtended by . Since
the measure of is the same as the measure of , which is the same as the value of , . Thus, the value of is .
