Question

Find the angle between two lines
2x - y + 3 = 0 and x + 2 y + 3 = 0 is
(a) 90°
(b) 60°
(c) 45​

Answer 1

Answer:

45

Step-by-step explanation:

on sloving the equation

slope(M1) of first equ. is= 2

and

slope(M2) of first equ. is= -x/2

thus it is clear that they r inclined to each other

so it's 45 degree

90 is not possible
