Homework Statement
As per the attachment
The Attempt at a Solution
for
a) sin58° = 32/hyp
hyp*sin58°=32
hyp=32/sin58°
hyp=32/0848
hyp=37.73
so to the nearest km between towns W & Y = 38km
b)cosθ=adj/hyp
cosθ=27/38
cosθ=0.710
θ=cos^-1(0.710)
θ=44.76
so to the nearest degree the angle = 45°
c)?^2=38^2-27^2
=√715
=26.73
so to the nearest km = 27km
do these look correct? I'm not sure with the last answer as if it is 27km its the same size as the other side and that does not look correct.
