Question : $\triangle \mathrm{ABC}$ is a right-angle triangle at $\mathrm{B}$. If $\tan \mathrm{A}=\frac{5}{12}$, then $\sin \mathrm{A}+\sin \mathrm{B}+\sin \mathrm{C}$ will be equal to:

Option 1: $1 \frac{5}{13}$

Option 2: $2 \frac{4}{13}$

Option 3: $3 \frac{1}{13}$

Option 4: $2 \frac{1}{13}$

Team Careers360 18th Jan, 2024

Correct Answer: $2 \frac{4}{13}$


Solution :
Given, $\tan\mathrm{A}=\frac{5}{12}$
Using Pythagoras theorem,
$AC^2 = AB^2+BC^2$
⇒ $AC^2 = 5^2 + 12^2$
⇒ $AC^2 = 25 + 144$
⇒ $AC^2 = 169$
⇒ $AC = 13$ units
⇒ $\sin \mathrm{A} = \frac{5}{13},$ $\sin \mathrm{B} = 1$ and $\sin\mathrm{C} = \frac{12}{13}$
So, $\sin
