∠ABD = 38°

Step-by-step explanation:

first find,

∠BDE = 180° - DEB° - DBE° ∠DEB is parallel to ∠DBE so both have 71° angle.

        = 180° - 71° - 71°

        = 38°

Step-by-step explanation:

ABD is the tangent chord angle, which is the half the measure of the intercepted arc:

On the other hand, the same arc BD is intercepted by the inscribed angle, which is the half of the intercepted arc measure:

Since m∠DEB = 71°, the angle ABD is of same size:

16
