Through the point (3,4) are drawn two straight line each inclined at 45* to the straight line x-y=2. find their equations and also find the area of triangle bounded by three lines.

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.
