B. 3.2 m
C. 2.8 m
D. 1.4 m
I am not sure what the ratio part means, but I thought maybe
using a proportion
(1.5/1)=(3/x)
so x=2
and then using a triangle (pyth. thm.) 3^2 + 2^2 = c^2 (slant height)
so I got sqrt (13) which equals 3.6
which the answer is supposed to be 3.2 but I do not think I did this correct because the answers are not close enough.
