Wow, that's along ladder, perhaps for the firemen!
From diagram,
(a)
sin(x) = 9 / 20 = 0.45
x = arcsin(0.45) = 26.74 degrees
(b)
height of wall ladder reaches
h = 20*cos(x) = 20*cos(26.74) = 17.86 m
I’m pretty sure the price before was £108.9 because 10% of £121 is £12.1 so if you subtract that you would get £108.9 I hope this helps
The answer is 10.35 because 63756 times 60 is 3825360 and 5280 times 70 is 369600 and if you divide those two answers it is 10.35
