Determine `x` so that the line passing through `3,4)a n d(x ,5)` makes an angle of `135^0` with the positive direction of the x-axis.

Text Solution

Verified by Experts

Slope of line passing through (3,4) and (x,5) is `(5-4)/(x-3)`. Also, inclination of line is `135^@`.
`therefore tan 135^@=(5-4)/(x-3)`
`rArr-1=(5-4)/(x-3)`
`rArr-x+3=1`
`rArrx=2`
