Kelsey did the following division problem. Her teacher says that the quotient she found is wrong. − 2 5 6 ÷ 1 1 3 − 17 6 ÷ 4 3 − 6 17 • 3 4 − 6 × 3 17 × 4 − 18 68 − 9 34 A. Identify what Kelsey did wrong in her calculations. B. Find the correct quotient, showing all of your calculations.

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°
