Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
A <u><em>circumscribed angle</em></u> is the angle made by two intersecting tangent lines to a circle
so
In this problem
BC and CD are tangents to the circle
BC=CD ----> by the Two Tangent Theorem
That means
Triangle ABC and Triangle ADC are congruent
so
Find the measure of angle BAC
In the right triangle ABC
substitute given value
Find the measure of angle BAD
Find the measure of minor arc BD
we know that
-----> by central angle
therefore
