Question

If the measure, in degrees, of arc AC and BD is 70° and
20°, respectively, then mLAPC is:
A
B.
P.
с
D
25°
O 45°
20°
50°

Answer 1

Answer:

∠ APC = 25°

Step-by-step explanation:

The secant- secant angle APC is half the difference of the intercepted arcs, that is

∠ APC = $\frac{1}{2}$ (AC - BD) = $\frac{1}{2}$ (70 - 20)° = 0.5 × 50° = 25°
