Just move over the two. When you change to standard form you want the x and y together and the constant by itself.

7x-4y+2=0
7x-4y+2-2=0-2
7x-4y=-2

Standard form: 7x-4y=-2

In the triangle above, what is sin A

Shkiper50 [21]

Answer:

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

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 ,

$\longrightarrow A = 30^o$

On using sin both sides ,

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

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

$\longrightarrow sin(A)=\dfrac{1}{2}$

Simplify by converting it into decimal ,

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

Hence option B is correct .

And we are done!
