The vertex of the angle must stay the same so F must always be in the middle.
Therefore you have EFG
And GFE
Using the combination formula, the probability that Rosa's mom chooses sausage and onion is given by:
B. .
The order in which the toppings are chosen is not important, hence the <em>combination formula </em>is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:
2 toppings are chosen from a set of 8, hence the number of options is given by:
.
Sausage and onion correspond to one topping, hence the probability is given by:
B. .

Answer:
250 feet
Step-by-step explanation:
If you draw out this situation, you would get a right triangle with a height of 200 (feet) and a base of 150 (feet). The wire is the missing length, or the 'hypotenuse' of this right triangle. You use the pythagoras thingie, and the formula is a^2 + b^2 = c^2.
a= 200
b= 150
c= ?
40,000 + 22,500 = c^2
62,500 = c^2
c = √62,500
∴ c = 250
