Question

Find the angle between two lines x + 5y = 11 and 5x − y = 1.

[GTU-SUMMER-2018]​

Answer 1

Step-by-step explanation:

y=-x/5+11/5

m1=-1/5

y=5x-1

m2=5

m1*m2=-1/5*5=-1

m1*m2=-1

two lines are perpendicular

@=90°

Answer 2

Find the angle between the lines (x + 5y - 1) and 5t - y = 11
