Answer:
y = 5.6
Step-by-step explanation:
Use Sine
Sine = 
Sine 45 = 
Sine of 18 is 0.309
0.309 =
Multiply 18 on both sides
0.309 x 18 = x 18
5.562 = y
Round to the nearest tenth:
5.562 = 5.6

Answer:
x=2
Step-by-step explanation:
18−7x=2x
Step 1: Simplif
18−7x=2x
18+−7x=2x
−7x+18=2x
Step 2: Subtract 2x from both sides.
−7x+18−2x=2x−2x
−9x+18=0
Step 3: Subtract 18 from both sides.
−9x+18−18=0−18
−9x=−18
Step 4: Divide both sides by -9.
