Answer:
the answer is actually 313 ft not a single person has answered the correct answer... smh
Step-by-step explanation:
313 ft
sinΘ = opp/hyp
Hailey's depth: x = 300sin30 = 150
partner's depth = 150 + 25 = 175
then, find horizontal distance
300^2 = 150^2 + b^2
b = 150 x square root of 3
then,
c^2 = (150 x square root of 3)^2 + (175)^2
c = 313.25
