Answer: I think it's 2
Step-by-step explanation: i am not dat good at math
The answer is A. The line indicates that the side are the same. Therefore it’s A.
Pythagoras’ theorem
a^2 + b^2 = c^2
Where a and b are two sides on a triangle and c is the hypotenuse.
Rearrange to find one to the sides that isn’t the hypotenuse.
a^2 = c^2 - b^2
a^2 = 25^2 - 10^2
a^2 = 625 - 100
a^2 = 525
(square root)
a = √525
= 5√21

(you have to include the zero, or else the answer would no longer be the nearest millionth! and you would be marked wrong)
