In ΔVWX, w = 520 cm, ∠W=93° and ∠X=68°. Find the length of x, to the nearest centimeter.

Pani-rosa [81]

Answer:

482.7972612 cm. Just round from here.

Step-by-step explanation:

Ah, the sine law questions. Ok so you know $\frac{sin(A)}{a} = \frac{sin(B)}{b} = \frac{sin(C)}{c}$ . If you don't, voila. Obviously, the variables are different but we can use the same formula. So, we have

$\frac{sin(X)}{x} = \frac{sin(W)}{w}$

Plug in:

$\frac{sin(68)}{x} = \frac{sin(93)}{520}$

The answer when solving for x is the above
