Question

In A DEF, what is the value of tan D? F 15 D 9 E

Answer 1

solution

For this case we can see that we have a right tirangle and we can find the value of tan D like this:

$EF=\sqrt[]{15^2-9^2}=12$

Then we have this:

$\tan D=\frac{12}{9}=\frac{4}{3}$

Then the final answer would be:

4/3
