Answer:
[tex]\large\boxed{\sf sin(A)=0.5}[/tex]
Step-by-step 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 ,
[tex]\longrightarrow A = 30^o[/tex]
On using sin both sides ,
[tex]\longrightarrow sin(A) = sin30^o[/tex]
As we know that the value of sin30° = 1/2. So;
[tex]\longrightarrow sin(A)=\dfrac{1}{2} [/tex]
Simplify by converting it into decimal ,
[tex]\longrightarrow \underline{\underline{sin(A) = 0.5}} [/tex]
Hence option B is correct .
And we are done!
