Answer:
Step-by-step explanation:
2X-5Y=6--------(1)
5X+2Y+8=0----------------(2)
Slope of line (1) is M1=2/5
And, slope of line (2) is M2= -5/2
Here, product of slope of line (1) and (2) is -1.
i.e. M1 x M2 = (2/5)x(-5/2) =1
If the product of two linear lines is -1, it means the lines are perpendicular to each other.
So, the angle between the given lines is 90 degree.
