Apply the Pyth Thm twice:
diagonal of base is sqrt(4^2+6^2).
Then the length of diagonal AB is L = [sqrt(4^2+6^2)]^2 + [sqrt(1)]^2
Thats is the answer hope it helps
let us assume that make inclination θ
with positive direction of x-axis then slope(m) of the line is given by
m=tanθ.
Hope it helps ☺☺
Mark as brainleist plz .
