Question

if theta is the acute angle between non -vertical lines having slope m1 and m2 then tan theta = [m1-m2/1+m1m2] heance find the angle with m1=3,m2=-2​

Answer 1

Explicação passo-a-passo:

$\displaystyle \tan( \frac{m1 - m2}{1 + m1 + m2} ) = \frac{3 - ( - 2)}{1 + 3( - 2)} = - 1$

$\theta = 135 \: degree$
