Find the equation of a line passing through `(1,2)`
and making angle of `30^0`
with y-axis
.
Text Solution
Verified by Experts
The correct Answer is:
N/a
Given that, angle with Y-axis `=30^(@)` and angle with X-axis `=60^(@)` `therefore` Slope of the line, `m=tan 60^(@)=sqrt3` So,the equation of a line passing through (1,2)and having slope `sqrt3`, is `y-2=sqrt3(x-1)` `rArr y-2=sqrt3x-sqrt3` `rArr y-sqrt3x-2+sqrt3=0`
