Parallel. This is pretty simple if you either a) Picture it in your head, or b) look at each option logically. lets try out b)

The last option does not really apply to lines, and is for angles. (unless your talking about the adjecent sides of an angle, but this would mean they meet at a vertex) Perpendicular, doesnt make sense because if they were perpindicular on a plane, (2-d) then it would be immpossible for BOTH to be parallel to a third line. This leaves the first option, which makes sense.

First, we are given that the inscribed angle of arc CB which is angle D is equal to 65°. This is half of the measure of the arc which is equal to the measure of the central angle, ∠O.

m∠O = 2 (65°) = 130°

Also, the measure of the angles where the tangent lines and the radii meet are equal to 90°. The sum of the measures of the angle of a quadrilateral ACOB is equal to 360°.

m∠O + m∠C + m∠B + m∠A = 360°

Substituting the known values,
130° + 90° + 90° + m∠A = 360°

The value of m∠A is equal to 50°.

<em>Answer: 50°</em>
