This is Pythagorean theorem.
We already know a and c.
a = 4 and c = 10
4² + b² = 10²
16 + b² = 100
Subtact 16 from each side.
b² = 84
Square root of each side:
b = ≈9.165 or √84
Hope this helps!

Turkey Sizes:
<span>small - 2kg - 3.9kg </span>
<span>medium - 4kg - 5.4kg </span>
<span>large - 5.5kg - 7.2kg </span>
<span>extra large - 7.3kg - 9.2kg </span>
<span>Turkey Prices: </span>
<span>Small / Medium - £5.99 per kg </span>
<span>Large / Extra Large - £4.99 per kg
</span>
3/4 lb x 14 persons = (3*14)/4 = 42/4 = 10.5 lbs
1 lb = 450 grams
10.5 lbs * 450grams/lb = 4,725 grams
1 kg = 1000 grams
<span>4,725 grams * 1kg/1000 grams = 4725 kg / 1000 = 4.725 kg.
4.725 kg is under the Medium size of the Turkey.
Medium sized turkey costs </span>£<span>5.99 per kg.
4.725 kg * </span>£5.99 per kg = £<span>28.30
A turkey would cost </span> £<span>28.30 for 14 people.</span>
He would maybe have 7.5 but I insist you the answer could be 8 too
