Question

In this figure, m∠BDA = ___° and m∠BCA = ___°.

Answer 1

Arc AB = 360-250 = 110

m(Inscribed angle) = 1/2 measure of intercepted arc. <BDA intercepts arc AB, so m<BDA = 1/2 * 110 = 55

m(Exterior angle formed by two tangents) = 1/2 difference of measure of intercepted arcs.

m<BCA = 1/2 (250 - 110) = 70
