Assume that lines that appear tangent are tangent. find the value of each variable.

since the angle of the arc is equal to 68° therefore angle b which is a central angle is ganna be equal to 68° which is the central angle while angle a is 34° which is an inscribed angle and inscribed angles are equal to half the subtended arc
