1. The slope of the line passing through E & F
= (√3 - 0) / (2 - 1)
= √3
Note : (d) = degree.
Then, let the inclination be x (d).
tan x = the slope of the line passing through E & F
____= √3
___x = 60 (d)
= (√3 - 0) / (2 - 1)
= √3
Note : (d) = degree.
Then, let the inclination be x (d).
tan x = the slope of the line passing through E & F
____= √3
___x = 60 (d)
