The vector wequalsaiplusbj is perpendicular to the line axplusbyequalsc and parallel to the line bxminusayequalsc. It is also tr
Likurg_2 [28]

Answer:

\theta=45^{\circ}

Step-by-step explanation:

We are given that the equation of lines

x+\sqrt 3y=1

(1-\sqrt 3)x+(1+\sqrt 3)y=8

According to question

The vector perpendicular to the lines is given by

i+\sqrt 3j and (1-\sqrt 3)i+(1+\sqrt 3)j

Therefore, the  angle between two vectors is given by

cos\theta=\frac{a_1a_2+b_1b_2}{\sqrt{a^2_1+b^2_1}\sqrt{a^2_2+b^2_2}}

Using the formula

cos\theta=\frac{1(1-\sqrt 3)+\sqrt 3(1+\sqrt 3)}{2\times 2\sqrt 2}

cos\theta=\frac{1-\sqrt 3+\sqrt 3+3}{4\sqrt 2}=\frac{1}{\sqrt 2}

cos\theta=cos 45^{\circ}

\theta=45^{\circ}

Hence, the acute angle between the lines is given by

\theta=45^{\circ}
