Answer 1

Answer:

SinA=1/2 TanA =2/1

Step-by-step explanation:

1/2 = sina 2/1 = tana

Answer 2

$Given \: Cos A = \frac{1}{2} \:--(1)$

$\implies Cos A = Cos \: 60\degree$

$\implies A = 60\degree \:$

$i ) Sin A = sin \:60 \degree\\ = \frac{\sqrt{3}}{2} \:--(2)$

$ii) tan A = tan \:60 \degree \\=\frac{Sin A}{Cos A} \\= \frac{\frac{\sqrt{3}}{2}}{\frac{1}{2}} \\= \sqrt{3} \:--(3)$

$iv) Cosec A = \frac{1}{Sin A } \\= \frac{2}{\sqrt{3}} \: --(4)$

$v ) Sec A = \frac{1}{Cos A } \\= 2 \: --(5)$

$vi ) Cot A = \frac{1}{tan A } \\= \frac{1}{\sqrt{3}} \: --(6)$
