Answer:

65

Step-by-step explanation:

TAB is an isosceles triangle by the point to tangent theorem theorem.

BAT and BAT are congruent because of the isosceles triangle definition.

CAT and ABT are right angles by the tangent theorem.  

Thus, CAB and CBA are both 90 - 65 = 25.

ACB is 130 because triangles' angles add up to 180.

APB is one half of ACB by the inscribed angles theorem.

The measure of the arc APB will be 230°. Then the correct option is D.

What is a circle?

It is the circle of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

We know that the tangents are equal.

Then triangle ΔATB is an isosceles triangle.

Then the angle ∠TAB and angle ∠TBA are congruent.

We know that the angle sum of a triangle is 180°.

∠TAB + ∠TBA + ∠ATB = 180°

               65° + 65° + z = 180°

                                  z = 50°

We know that the radius and tangent of circle make 90°.

And the angle sum of quadrilateral is 360°.

∠TAC + ∠TBC + ∠ATB + ∠ACB = 360°

                   90° + 90° + 50° + y = 180°

                                                y = 130°

Then the measure of the arc APB will be

x = 360° – 130°

x = 230°

The measure of the arc APB will be 230°.

Then the correct option is D.
