more easily then Adam since he can try to guess it more easily???
I'm not good at explaining but yeah -
10. tan(30) = l / 6√3
l = tan(30) x 6√3
l = 6
cos(30) = 6√3 / y
y = 6√3/cos(30)
y = 12
11. tan(30) = c/30
c = 30 x tan(30)
c = 10√3
cos(30) = 27/w
w = 27/cos(30)
w = 18√3
12.
sin(60) = 36/y
y = 36/sin(60)
y = 24√3
tan(60) = 36/x
x = 36/tan(60)
x = 12√3
