Question

In the triangle above, what is sin A

Answer 1

`\large\boxed{\sf sin(A)=0.5}`

Explanation:

A right angled triangle is given to us and we would like to find out the value of sin(A) .

From the triangle we can see that the measure of angle BAC is 30° . Therefore ,

`\longrightarrow A = 30^o`

On using sin both sides ,

`\longrightarrow sin(A) = sin30^o`

As we know that the value of sin30° = 1/2. So;

`\longrightarrow sin(A)=(1)/(2)`

Simplify by converting it into decimal ,

`\longrightarrow \underline{\underline{sin(A) = 0.5}}`

Hence option B is correct .

And we are done!
