Determine the distance D between the line l x 2514t y 1465
Determine the distance D between the line: l: x = 25+14t, y = 14-65t, z= 59+6t
and the plane P: 5x + 2y +10z = 98 Make sure to keep your answer exact,
Solution
The equation of line can be written as
(x-25)/14= (y-14)/-65=(z-59)/6=t
So, l=14, m=-65, n=6
The equation of plane is 5x+2y+10z-98=0
Comparing with ax+by+cz+d=0, we get
a=5, b=2, c=10
We know that the angle between them is given by
sin= (al+bm+cn)/(a²+b²+c²)(l²+m²+n²)
sin= (5*14)+(2*-65)+(10*6)/5²+2²+10²14²+(-65)²+6²
sin= (70-130+60)/1294457=0
Sin=sin0°
so, =0° Ans.
