What is the formula for the following geometric sequence? 3, 12, 48, 192, ...

an = 4 · 3n - 1
an = 3 · (-4)n - 1
an = 3 · 4n - 1
an = (1/4) · 3n - 1

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
