The angle between the straight lines `(x+1)/2=(y-2)/5=(z+3)/4a n d(x-1)/1=(y+2)/2=(z-3)/(-3)` is `45^0` b. `30^0` c. `60^0` d. `90^0`

Explanation

To find the angle between the two straight lines given in the symmetric form, we can follow these steps:

### Step 1: Identify the Direction Ratios
The equations of the lines are given as:
1. \((x+1)/2 = (y-2)/5 = (z+3)/4\)
2. \((x-1)/1 = (y+2)/2 = (z-3)/(-3)\)

From these equations, we can extract the direction ratios.
