Sighting from Paula's location and the 42-degree angle, the height of the glider is the "opp side" of a triangle whose hypotenuse is 3280 ft.

The sine function best brings together the info we have and want:

sin 42 degrees = opp / hyp = height / 3280 ft.

Mult. both sides of this equation by 3280 ft, we get height = 2195 ft.

hi here is what  I got

opposite the angle (42)

Using trigonometric ratios:

Sin = Opposite/Hypotenuse

Sin(42) = Opposite/3280

Cross multiply

Opposite = sin(42) x 3280

Opposite = 2194.7 feet (1 decimal place)

nasty-shy [4]

Answer:

6 hours and 45 minutes

Step-by-step explanation:

First, convert 12 hours into minutes.

12*60=720

Convert 5 hours to minutes and add 15

5*60=300+15=315

Subtract 720 from 315.

720-315=405

Convert into hours and minutes.

405/60=6.75

0.75 of an hour is 45 minutes so the answer is 6 hours and 45 minutes.
