Question

eric is flying an airplane at an altitude of 2200 feet. he sees his house on the ground at a 45⁰ angle of depression. what is Eric's horizontal distance from his house at this point?

Answer 1

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
