Answer:
Last option 527.7 ft
Step-by-step explanation:
From the diagram attached we can see the angle of depression is 80.2 which is equal to ∠ACB (alternate angles)
Height of the deck AB = 520 ft. and we have to calculate the distance H between the tourist and her friend.
Sin ∠ACB = 
Now we apply sin rule sin 80.2 = 


So the tourist and her friend are 527.7 ft apart.
Answer:
y=-1x+1
Step-by-step explanation:
Here are 4 questions I answered
Ok so easy. So the equation is y=mx+b where m is the slope. You get slope by doing y2-y1 /x2-X1. Ok so I'm assuming you know which one is y1 and which one is y2 if not comment back and I answer.
