(angle between two straight lines )
# find the angle between the lines :
x cos 40 degree + y sin 40 degree = 3 and
x sin 40 degree - y cos 40 degree = 5
#salute u if u solved it

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
