ic's horizontal distance from his house at this point?
1 answer:
Answer:
2200 feet
Step-by-step explanation:
1. Find necessary angles
45˚ + 45˚ = 90
so airplane and height is 45˚ in between
d = distance
cos 45 = 2200/d
d = 2200/cos 45
d ≈ 3111.27 > all of the answers
If it is from ground to house then its 2200 ft, same as plane to ground
