Answer: (should be) A
Step-by-step explanation: I've done the same test before
Find the tangent of the angle, using the height (472) minus the elevated height of the camera (2) which would be 470 meters, and also the distance away from the shuttle, which would be 750. Opposite divided by adjacent would make the tangent 0.626...so using a triangle chart, the closest whole numbered angle 0.626 would be to is 32 degrees.
Thats for questions 3 - 8 that you didn't answer. I'm not quite sure how to answer the last two though.
Answer:
30mph faster
Step-by-step explanation:
first you must find how fast the train can go in 1 hour
that is 60mph, then multiply 60 and 2.5
60x2.5 = 150mph then,
150 - 120 =30mph
very sorry if this is wrong
