Answer:

x = 10.2 m

Step-by-step explanation:

law of sines:

sin 30° / x = sin 69° / 19

cross-multiply:

.5(19) = sin 69°x

x = .5(19) / sin 69°

x = 9.5/.934

x = 10.2

What is Sine Law?

Law of sines defines the ratio of sides of a triangle and their respective sine angles are equivalent to each other. The other names of the law of sines are sine law, sine rule and sine formula.

Here, Law of sines:

[tex]\frac{Sin A}{a} =\frac{Sin B}{b} = \frac{Sin C}{c}[/tex]

sin 30° / x = sin 69° / 19

1/2x =  sin 69° / 19

cross-multiply:

19/2 = sin 69°x

x = 9.5 / sin 69°

x = 9.5/0.934

x = 10.2

Thus, the value of x with the help of sine law is 10.2 units.
