An airplane descends 1.6 miles to an elevation of 8.05 miles. Find the elevation of the plane before its descent.

9.65 miles

Step-by-step explanation:

Given:

Final elevation = 8.05 miles

Change in elevation = 1.6 miles

Let Initial elevation which is the elevation before descent = x

Initial elevation - change in = final elevation

(-ve) sign because it was a descent

x - 1.6 = 8.05

x = 8.05 + 1.6

x = 9.65 miles

Hence, elevation before descent is 9.65 miles

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°
