Worth 100 points, but please answer if you know the correct answer. Find the value of each variable. The dot represents the center of the circle. Lines that appear tangent are tangent.

a is 29°

b is 61°

c is 44°

Step-by-step explanation:

a,b, and c are all inscribed angles which means they are 1/2 the measure of the arc they intercept. To find the measure of the arc on the circle that angle b intercepts, you need to subtract 58° from 180° because the measure of the arc of a semi-circle is 180°. 180°-58°= 122° so b is half of that, or 61°
