A) \[52x+89y+519=0\]
B) \[\beta \]
C) \[89x+52y+519=0\]
D) \[89x+52y-519=0\]
Correct Answer: A
Solution :
Slopes of \[AB\] and BC are ? 4 and \[\frac{3}{4}\] respectively. If \[\alpha \] be the angle between \[AB\] and \[BC\], then \[\tan \alpha =\frac{-4-\frac{3}{4}}{1-4\left( \frac{3}{4} \right)}=\frac{19}{8}\] .....(i) Since \[AB=AC\] \[\Rightarrow \angle ABC=\angle ACB=\alpha \]You need to login to perform this action.
