Step 1. Expand

2 - a = a - 1.8

Step 2. Add a to both sides

2 = a - 1.8 + a

Step 3. Simplify a - 1.8 + a to 2a - 1.8

2 = 2a - 1.8

Step 4. Add 1.8 to both sides

2 + 1.8 = 2a

Step 5. Simplify 5 + 1.8 to 3.8

3.8 = 2a

Step 6. Divide both sides by 2

3.8/2 = a

Step 7. Simplify 3.8/2 to 1.9

1.9 = a

Step 8. Switch sides

a = 1.9

Inside a toy truck, there is a gear that rotates to (3, −8) when the steering wheel is turned to the left. What is the sine valu
Marianna [84]
This is the the concept of trigonometry, to get the sine value of the the function given we shall proceed as follows;
Using Pythagorean theorem, the hypotenuse of the triangle will be found as follows;
The side length will be 8 units since the y-coordinate is -8
The side width will be 3 units since the x- coordinate is 3  
c^2=a^2+b^2
c^2=(3)^2+(-8)^2
c^2=9+64
c^2=73
c=sqrt(73)

Therefore the sine value will be:
sin x=3/sqrt(73)
multiply both numerator and denominator by sqrt(73) we get:
sin x=(3√73)/73

Therefore the answer is A]
