Question

A ray of light through B (3,2) is reflected at the point A (0,β) on the y-axis and passes through C (4,3) then β is​

Answer 1

$answer$

I.e reflected on x-axis

BC=

$\sqrt{1 + 1} = \sqrt{2}$

OB=OC=1/√2

O=(7/2,5/2)

AC=AB

$\sqrt{ {4}^{2} + { ( \beta - 3 )}}^{2} = \sqrt{ {3}^{2} + {( \beta - 2)}^{2} }$

Squaring on both sides

We get

β =7/11
