Question

Solve the following
sin A=1/√2
cos A=?
ii) sin A= √3/2
tan A=?​

Answer 1

Answer:

i) 1/√2

ii) √3

Step-by-step explanation:

i) Sin A = 1/√2

As we know that Sin 45° is 1/√2

So, A = 45°

To find, Cos A = Cos 45°

So as we know, Cos 45° = 1/√2

ii) Sin A = √3/2

We know, Sin 60° = √3/2

So, A = 60°

Now, tan A = tan 60°

tan 60° = √3

Hope it helps!

Answer 2

Answer:

$i) \frac{1}{ \sqrt{2} }$

$ii) \sqrt{3}$

Step-by-step explanation:

i) Sin A = 1/√2

Sin 45° = 1/√2

So, A = 45°

Cos 45° = 1/√2

ii) Sin A = √3/2

Sin 60° = √3/2

A = 60°

Cos 60° = √3

Hope it helps you!
