Answer
(i) 0
Let inclination be θ.
By formula,
⇒ m = tan θ
⇒ 0 = tan θ
⇒ tan θ = tan 0°
⇒ θ = 0°.
Hence, inclination of line = 0°.
(ii)
Let inclination be θ.
By formula,
⇒ m = tan θ
⇒ = tan θ
⇒ tan θ = tan 60°
⇒ θ = 60°.
Hence, inclination of line = 60°.
(iii) 0.7646
Let inclination be θ.
By formula,
⇒ m = tan θ
⇒ 0.7646 = tan θ
⇒ tan θ = tan 37° 24'
⇒ θ = 37° 24'.
Hence, inclination of line = 37° 24'.
(iv) 1.0875
Let inclination be θ.
By formula,
⇒ m = tan θ
⇒ 1.0875 = tan θ
⇒ tan θ = tan 47° 24'
⇒ θ = 47° 24'.
Hence, inclination of line = 47° 24'.
