Given: Tangent A B →  and A C → to ⊙ O m ∠ A C B = 68 ° Find: a) m B C ⌢ b) m B D C ⌢ c) m ∠ A B C d) m ∠ A To determine

(a)

To find:

mBC when AB and AC are tangent to O, mACB=68°.

Explanation

Corollary:

The measure of an angle formed by a tangent and a chord drawn to the point of tangency is one-half the measure of the two intercepted arc.

Calculation:

mBC when AB and AC are tangent to O, mACB=68°.

To determine

(b)

To find:

mBDC when AB and AC are tangent to O, mACB=68°.

To determine

(c)

To find:

mABC when AB and AC are tangent to O, mBC=136°.

To determine

(d)

To find:

mA when AB and AC are tangent to O, mBC=136° and mBDC=224°.
