Question

pls dont write the wrong answer

Answer 1

$&#10144 \: \: \tan\theta = \cot\theta$

so the Value of theta = 45 °

Now put the value of theta in equation

$&#10144 \: \: 2 \tan\theta + { \cos }^{2} \theta \: \: \: \: \: \: \: \\ \\ &#10144 \: \: 2 \tan(45) + { \cos}^{2} 45 \\ \\ &#10144 \: \: 2 \times 1 + { (\frac{1}{ \sqrt{2} } )}^{2} \: \: \: \: \: \: \: \\ \\ &#10144 \: \: 2 + \frac{1}{2} = \frac{5}{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
