a parallel line has the same gradient, so the gradient would be 3 1/3
a perpendicular line has the negative inverse gradient of the original (eg. if the original gradient is 4/3 then the perpendicular gradient would be -3/4 (all you have to do is change the +/- sign and flip the fraction), so in your case the gradient of the perpendicular line would be -3/10 (since 3 1/3 = 10/3)
360 - 160 - 60 = 140
<span><y = 1/2 * 140 = 70
Hope this helps
