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!

Grant spent half of his weekly allowance. Then he earned $5 back by doing the dishes. What is his weekly allowance if he ended w

goldfiish [28.3K]

Answer:

Grant's weekly allowance is $20.

Step-by-step explanation:

We know that Grant ended with $15. We can say that Grant's weekly allowance is x.

x/2 + 5 = 15

Now to solve:

x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)

x/2 = 10

x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)

x = 20

Grant's weekly allowance is $20.
