Hey need help to interpret the following problem , not able to understand what exactly we need to find
Andreas is standing 20 meters in front of the 100-meter tall Statue of Liberty on the platform where the statue sits. If the platform is 40 meters above sea level and if Andreas descends directly to ground level, how many meters does he need to directly back up to have the exact viewing angle of the Statue of Liberty he had while standing on the platform?
There is nothing “Pythagoras theorem” in the problem. Hint: make a diagram - what’s that you need to find?
you can probably set a proportion-
so
140/x = 100/20
where 140 = platform plus the statue
100 = statue above platform
20 = andreas distance from the statue when he is on the platform
x = andreas distance from the statue when he is on ground floor
by solving you would get x = 28
so he would have to back up by 8 m
