The hill in the form of a right triangle has its foot at (19, 3). The inclination of the hill to the ground is 45°. Find the equation of the hill joining the foot and top.

Answer»

θ = 45°

Coordinate of foot of hill = (19, 3) let equation of line be y = mx + c

m = tan θ = tan 45° = 1

⇒ y = x + c

Substituting y = 3 & x = 19, 3 = 19 + c ⇒ c = -16

∴ Equation of line:

y = x - 16

= x - y - 16 = 0
