Question

22. The angle between the lines 2x-
Y+3=0&x+2y+3=0 is​

Answer 1

Answer:9 by 14

Step-by-step explanation:

Answer 2

Answer:

angle between two lines

tan x = | M -m/ 1+ Mm |

now slope of line 2 x - y + 3 =0

reduce this equ. in y = M x + c

then 2 x + 3 = Y

so slope M = 2

similarly slope of second line m = -1/2

so angle between two lines

tan x= | 2 - ( -1/2) | / | 1 + 2 *(-1/2) |

tan x = | 5/2 | / | 0|

tanx = not define

x = 90 degree
