laws of sines!!!!! find X. Round the the nearest tenth!!!! please help!!!!! asap!!!! trigonometry!!!!!
1 answer:
Answer:
21.4°
Step-by-step 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°

Answer:
I think it might be D. 15, Im not sure though, If its not im very sorry.

-2x + 12 < - 4......subtract 12 from both sides
-2x + 12 - 12 < -4 - 12....simplify
-2x < -16...divide both sides by -2, changing the inequality sign
(-2/-2)x > -16/-2....simplify
x > 8
