through the point 3, 4 are drawn to straight lines each inclined at 45 degree to the straight line x - y= 2 . find the equations and find also the area included by the three lines

Question

Arun · Answer

Dear Kamal

by using the formula

tanA=modulas of (m₁-m₂)/(1+m₁m₂)

where A=45 and m₁=+1

we can fine m₂ from that we get two values

so we get two lines.

using the three lines we find the oint of intersections.

from the area formula we get the area covered by the triangle.
