Answer:
Velocity (against wind) = 1,890 / 3 = 630 mph
Velocity (with the wind) = 1,890 / 2.5 = 756 mph
Plane speed (still air) = 630 + wind speed
Plane speed (still air) = 756 - wind speed
Adding both equations equals
2 * Plane speed (still air) = 1,386
Plane Speed = 693 mph

Step-by-step explanation:
A building 62 feet tall casts a shadow 21 meters long . At what angle is the sun shining on the building?
We solve this question using the Trigonometric function of Tangent
tan x = Opposite/Adjacent
Where
Opposite = 62ft
Adjacent = 21 ft
x = Angle
Hence,
tan x = 62/21
x = arc tan (62/21)
x = 71.288262125°
Approximately = 71.3°

Step-by-step explanation:
x-4.2>5.5= 9.7 Collin forgot to change his negative to a positive when adding +4.2 +4.2 the inequality. He was supposed to change the negative to positive add 4.2 to 5.5 which would give him a positive 9.2
