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

Answer:

C = 6

D = 10

Step-by-step explanation:

C + 5 = 11

C + 5 -5 = 11 -5

C = 6

D + 4 = 14

D + 4 -4 = 14 -4

D = 10

Answer:

HOPE I HELP YOU

ANY HELP AM ON IT

We are told that n and m are parallel.

The angle that measures 105 degrees is supplementary with the alternate interior angle of the angle which measures (3x - 18) degrees. Supplementary angles add to equal 180 degrees, so we can make an equation by first finding the measure of the alternate interior angle.

180 - 105 = 75

The alternate interior angle measures 75 degrees, so we can set that equal to 3x - 18 to solve for x since alternate interior angles are congruent.

75 = 3x - 18

93 = 3x

31 = x

x = 31
