Step-by-step explanation:
1.75-0.8= 0.95m
0.95/2. to get equal halves would be 0.475m just under half a meter
<span> (0, 2) (3, 0)
slope = (2-0)/(0-3) = -2/3
perpendicular lines, slope is opposite and reciprocal
so </span><span>the slope of a line that is perpendicular to the line is 3/2
answer
3/2</span>
