For this question, we want to find out the greatest amount of area of pizza for the least amount of money:
So we have two pizzas with a 10 in. diameter. Let us take one of those pizzas.
The formula for area of a circle is
; So the area for one of these 10 in. pizzas would be 
or 25
.
We have two of these pizzas, so the total area that we would get with $14 would be 25*2 or 50.
For the second case, we have one pizza with a 14 in. diameter.
The area of this pizza will be
or 49.
So for $15 we can buy 49 worth of pizza.
The best deal would be to buy the two medium pizzas of 10 inch diameter, because for $14, you get 50.

Answer:
1. No
2. No
3. Yes
4. Yes
Step-by-step explanation:
The diagram has been attached
The total angle in a triangle is 180°
<CAD=45°
<ACD=90°
Therefore <ADB=45°
1. ∠ADB = 30° no
ADC = 90 - 45 = 45
∠BDC = 90 - 65 = 25
∠ADB = 45 - 25 = 20
2.△ABD ∼ △ACD no going
by law of sines
3.CD = 33.7 centimeters => yes
4.BD = 37.2 centimeters => yes
