Assuming each story is the same height
910=65 stories put together
910=65 times (height of each story)
910=65h
divide both sides by 65
14=h
each story is 14 feet
the equation is 910=65h
I believe its 45 because a right angle equals 90 degrees and if you multiply 45 and 2, it'll give you a right angle(90 degrees)
It’s 10. This is because 27/3 is 9 so the ratio is by 9

1x500=500
500x4=2000
500x3=1500
