Laws of find x. round to the nearest

x = 31.8°

Step-by-step explanation:

Law of sines:

sin (x) / 12 = sin(75°) / 22

Multiply both sides by 12

sin (x) = (sin(75°)/22) x 12

sin (x) = 0.5269

Inverse Sine:

x = sin−1(0.5269)

x = 31.8°

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
