Find the equation of the line passing through (2, 2тИЪ3) and inclined with x тАУ axis at an angle of 75o.



Answer -

Given:

A line which ispassing through (2, 2тИЪ3), the angle is 75o.

By using the formula,

The equation of lineis [y тАУ y1┬а= m(x тАУ x1)]

Here, angle,┬а╬╕ =75o

The slope of the line,m = tan ╬╕

m = tan 75o

= 3.73 = 2 +┬атИЪ3

The line passingthrough (x1, y1) =┬а(2, 2тИЪ3)

The required equationof the line is┬аy тАУ y1┬а= m(x тАУ x1)

Now, substitute thevalues, we get

y тАУ┬а2тИЪ3┬а= 2+┬атИЪ3┬а(x тАУ 2)

y тАУ 2тИЪ3 = (2+┬атИЪ3)x тАУ 7.46

(2 +┬атИЪ3)x тАУ y тАУ 4= 0

тИ┤ The equation of theline is┬а(2 +┬атИЪ3)x тАУ y тАУ 4 = 0
