Answer 2

Answer:

theta =A

Step-by-step explanation:

${tan}^{2} a \: = { \frac{ {sin}^{2} a}{ {cos}^{2}a } }^{2}$

${ \cot }^{2} a = \frac{ {cos}^{2}a }{ {sin}^{2}a }$

$\frac{ {sin}^{2}a }{ {cos}^{2}a } \times {cos}^{2} a = {sin}^{2}a$

$\frac{ {cos}^{2}a }{ {sin}^{2}a } \times {sin}^{2} a = {cos}^{2} a$

${sin}^{2} a + {cos}^{2} a = 1$
