Questions
The equation of base of an equilateral triangle is and one vertex is origin then the length of the side is
a
103
b
109
c
1039
d
1033
detailed solution
Correct option is D
The perpendicular distance from a point Px1,y1 to the line ax+by+c=0 is ax1+by1+ca2+b2 The perpendicular distance from a point (0,0) to the line 4x+3y−25=0 is 40+30−2516+9=255=5 This is height h of the equilateral triangle. If a be the side of an equilateral triangle, then a=2h3Hence,a=253=1033 Therefore, the length of the side of equilateral triangle is a=1033Talk to our academic expert!
