Question

laws of sines!!!!! find X. Round the the nearest tenth!!!! please help!!!!! asap!!!! trigonometry!!!!!​

Answer 1

21.4°

Explanation:

Law of sines:

Triangle ABC:

sin A / a = sin B / b = sin C / c

In this case:

sin (x) / 12 = sin(42°) / 22

Multiply both sides by 12

sin (x) = (sin(42°)/22) x 12

sin (x) = 0.3650

Inverse Sine:

x = sin−1(0.3650)

x = 21.4°
