Question

If tanA=12/5 then, the value of sinA= ?

5/12

12/13

5/13

12/5​

Answer 1

if tan A =12\13 then the value of sin A=12\13

Answer 2

$\tan(a) = \frac{p}{b} = \frac{12}{5}$

$h = \sqrt{ {p}^{2} + {b}^{2} } \\ = \sqrt{ {12}^{2} + {5}^{2} } = \sqrt{144 + 25} = \sqrt{169} = 13$

$\sin(a) = \frac{p}{h} = \frac{12}{13}$
