One train is going 85 mph and the other 75 mph
The picture is in the attachment.
x- horizontal distance between Susan and a bird
7 - x - horizontal distance between Math and a bird;
h / x = tan 20° = 0.364
h / (7 - x) = tan 50°= 1.192
----------------------------------
h = 0.364 x
0.364 x / (7 - x ) = 1.192
0.364 x = 1.192 ( 7 - x )
0.364 x = 8.344 - 1.192 x
1.556 x = 8.344
x = 8.344 : 1.556 = 5.362 km
h = 0.364 · 5.362
h = 1.952 km
.. the bird is at height of
1.952 km from the ground.
The ratio would be 36 to 18
because 9*4=36
and 18 is 18 lol
so (calculator) 1,080/9=120
120
20*18=180
100*9=900
so
idek man this is hard as hell,I tried tho,try to do the rest of the problem from what I have set up
