21.4 degrees

Step-by-step explanation:

Using the law of sines

sin 42         sin x

=

22             12

Using cross products

12 sin 42 = 22 sin x

Divide each side by 22

12/22 sin 42 = sin x

taking the inverse sin of each side

sin ^-1 (12/22 sin 42) =  sin ^-1 (sin x)

sin ^-1 (12/22 sin 42) =  x

21.40637223 =x

To the nearest tenth

21.4 =x

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
