Do they want you to label everything, what are they looking for?
I believe this is the answer
A) 24
B) -3
Total billed amount of fridge including VAT = $480
Let us assume the price of the fridge before the VAT is added = $x.
20% of VAT is added.
20% of x is 0.20x.
Total amount = 480.
Let us set an equation to find the value of x.
<h3>x+0.20x = 480.</h3>
1.20x = 480.
Dividing both sides by 1.20, we get
1.20x/1.20 = 480/1.20
x= 400.
<h3>Therefore, $ 400 is the price of the fridge before the VAT added.</h3>
Answer:
x = 2
Step-by-step explanation:

subtract 20x from both sides

divide both sides by -14

add 1 to both sides

Answer:
90° + (γ/2)
Step-by-step explanation:
The angles in ΔADB have a sum of 180°, so ...
(A/2) +(B/2) + ∠ADB = 180°
and so do the angles of ΔABC:
A + B + γ = 180°
Dividing this second equation by 2 gives an expression for (A/2) +(B/2) that we can substitute into the first equation:
A/2 +B/2 +γ/2 = 90°
A/2 +B/2 = 90° -γ/2
Putting this in the first equation, we have ...
(90° -γ/2) + ∠ADB = 180°
∠ADB = 90° +γ/2 . . . . . . . . . . add (γ/2 -90°)
