Questions
The acute angle between the lines and is
a
120°
b
60°
c
90°
d
30°
detailed solution
Correct option is B
If is acute angle between two lines y=m1x−a and y=2+3x+8 then tanθ=m1−m21+m1m2Hence, tanθ=2−3−2+31+2−32+3=−231+4−3=3It gives θ=60°Therefore, the acute angle between the given lines is θ=60°Talk to our academic expert!
