A plane rises from takeoff and flies at an angle of 90° with the horizontal runway when it has gained 400 feet find the distance
that the plane has flown.
1 answer:
Answer:
2879ft
Step-by-step explanation:
The level runway (x), height gained (h), and distance travelled (r) form a right-angled triangle with base angle
