Answer:
Explanation:
An isosceles triangle is one with two equal lengths.
To find the lengths of the sides with coordinates
(
x

)
,
(

,
y

)
we use Pythagoras' theorem

Add what they ate
2/3 + 1/4 =
11/12
Then subtract that from the whole pizza
12/12 - 11/12 =
1/12
1/12 of the pizza is left
The answer in scientific notation is <span>5.8 x 10 <span>7.( The 10 is raised by 7).</span></span>
