Question

Find the equations of the lines through the points (3,2) which makes acute angle of 45 degree with the line x-2y = 3 .

Answer 1

@Abhisar

Answer 2

Are you familiar with vectors?

Answer 3

Plz solve it using Co-ordinate geometry

Answer 4

I will not solve it for you, and yes, we will use coordinate geometry.

Answer 5

Ok....Just plz help me.

Answer 6

You might want to start by drawing a fairly accurate diagram. This may not solve the problem for you, but would at least give you a way to estimate the slope and y intercept of the line(s) in question.

Answer 7

Use the formula:
tan(angle) = (m1-m2)/(1+m1m2)

Answer 8

plug in for m and u got your answer

Answer 9

@boldjon gave you a good method to find the slope of the line you are looking for.

Answer 10

Ok

Answer 11

so? have u found it

Answer 12

Found what? To answer the original question, we'll need to find another point, besides (3,2), through which the unknown line passes. I'm still struggling with a drawing that would show one unknown line that makes an angle of 45 dedgrees with the line x-2y=3.

Answer 13

Now, that's good! thank you.
