Since the area of a square is equal to the square of one of its side's length, then the area should be equivalent to . ---> equation (1) By using pythagoras rule which states that the ---> equation (2) where the opposite side's length is 8 and the hypotenuse side's length is 10 by substituting by the values in equation (2) therefore, substitute this value in equation (1) then where A is the area of the square whose side is x
The smallest triangle is not going to be determined by the a plus sign between the largest square and one of the small ones. That eliminates the two top answers.
A right triangle has the pythagorean equation associated with it.
That's a^2 + b^2 = c^2
Both the top right answer and the bottom left answer are eliminated because they are not of this form.
The largest side is c so to find x you need to subtract 8^2 from 10^2
