Question

A small airplane climbs at an
angle of 18° with the ground.
Find the horizontal distance it
has flown when it has reached an
altitude of 800 m.
a) 2,462 m
b) 260 m
c) 761 m
d) 2,588 m
e) 841 m

Answer 1

Answer:

Choice C, 761 m

Step-by-step explanation:

let horizontal distance be x

in the right triangle, cos= adj/hyp

cos(18)=x/800

x=cos(18)×800= 760.845≈ 761
