Answer:
3
Step-by-step explanation:
The slope of the line passing through the points is
m = (y2-y1)/(x2-x1)
= ( 1-2)/(8-5)
= -1/3
The slope that is perpendicular is the negative reciprocal which is
- ( 1/(-1/3)
+ 3/1
The perpendicular slope is 3
Answer:
<em>h=</em> 10m
Step-by-step explanation:
<em>1/2x12x18.2=109.2m squared</em>
<em>then u divide it by 21.8</em>
<em>109.2m2/21.8m/ 1/2=10m</em>
<em>h=10m</em>
