Question

find acute angle between line 3
$3x - y = 0 \\ 2x + y = 3$
​

Answer 1

Step-by-step explanation:

$\huge\underline{\underline{\sf ANSWER}} \\ slope \: of \: line \\ 3x - y = 0 \: is \: 3 \\ slope \: of \: line \\ 2x + y = 3 \: is \: - 2 \\ \\ \\ \tan(a) = | \frac{m2 - m1}{1 + m1m2} | \\ \tan(a) = | \frac{ - 5}{ - 5} | \\ \tan(a) = 1 \\ a = 45 \\ \\ therefore \: \\ angle \:between \: lines \: is \: 45 \: or \: \frac{\pi}{4}$
