Question
In the following Figure. AD = 4 cm, BD = 3 cm and CB = 12 cm, find the cot θ.
Options
\[\frac{12}{5}\]
\[\frac{5}{12}\]
\[\frac{13}{12}\]
\[\frac{12}{13}\]
Solution
We have the following given data in the figure, `AD=4cm, BD=3 cm, CB=12 cm`
Now we will use Pythagoras theorem in, ΔABD
`AB=sqrt(3^2+4^2)`
= 5 cm
Therefore,
`cot θ =( CB)/(AB)`
=`12/5`
