Answer:
x=11
Step-by-step explanation:
1 foot is the distance from the climber to the horizon
(1,7), since that's the point where both lines intersect.
Answer:
x= 47
18+2 201 i ≈0.382978723+0.603295612i
x= 47
−2 201 i+18 ≈0.382978723−0.603295612i Hopefully this makes just the same amount of sense as this question
