cosθ-1/2=0

cos θ=1/2=cos π/3,cos(2π-π/3)

θ=π/3,5π/3

Answer:

6a) x = -6

Let's solve your equation step-by-step.


14= 2x + 26


Step 1: Flip the equation.


2x + 26 = 14


Step 2: Subtract 26 from both sides.


2x + 26 − 26 = 14 − 26


2x = −12


Step 3: Divide both sides by 2.


2x/2 = −12/2


x=−6

--------------------

7a) x = 4.25

Let's solve your equation step-by-step.


−30 =4 − 8x


Step 1: Simplify both sides of the equation.


−30 = 4 − 8x


−30 = 4 + −8x


−30 = −8x + 4


Step 2: Flip the equation.


−8x + 4 = −30


Step 3: Subtract 4 from both sides.


−8x + 4 − 4 = −30 − 4


−8x = −34

x=17/4 (Decimal: 4.25)

---------------------------------

8a) x = 8

Let's solve your equation step-by-step.


3(x − 4) = 12


Step 1: Simplify both sides of the equation.


3(x − 4) = 12


(3)(x) + (3)(−4)= 12(Distribute)


3x + −12 = 12


3x − 12= 12


Step 2: Add 12 to both sides.


3x − 12 +1 2 = 12 + 12


3x = 24


Step 3: Divide both sides by 3.

3x/3=24/3

x=8
