The line with equation a – b = 0 coincides with the terminal side of an angle x in standard position in quadrant iii. what is tan x?

Since the  line with equation x−y=0 coincides with the terminal side of an angle θ in standard position in Quadrant III, we can compute tan by using: line is y = x and its slope m = tan θ = 1 and obviously we can conclude that theta will be equal to 45 degrees.
