Answer:
135 degrees
Step-by-step explanation:
let the inclination be theta.
Here, theta is the angle made by line AB in a positive direction.
So, 0 + 45 = 180
or, 0= 180-45
Therefore, 0=135
Hence, The inclination is 135
( Im not sure with my answer so check it yourself plz. The answer could be 45 degrees too)
(same book btw look at pg 142 example 1)
