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°

Fill in the blanks to show the steps in solving the inequality -2x + 12<-4
professor190 [17]
-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
