89 squared equals 7,921.
13
5 squared = 25 8 squared = 64 64+25=89
89
The square root of 89 is approximately 9.4 so 9 and 10 are the closest whole numbers. You could also notice that 9 squared is 81 and 10 squared is 100 which are the closest perfect squares to 81.
-- Since you mentioned "hypotenuse", we know you must be talking abouta right triangle.-- Since you're asking for the length of the hypotenuse, we know that the '8'and the '5' must be the lengths of the legs.hypotenuse squared = 8 squared + 5 squaredh squared = 64 + 25h squared= 89h = sqrt(89) = 9.434 (rounded)Angles:-- Since the triangle is a right triangle, one of its angles is 90 degrees,and the other two angles add up to 90 degrees.-- Cosine of one acute angle = 8/sqrt(89).

It is: 25+64 = 89
Pythagorean Eq'n Hypotenuse^(2) = side(1)^(2) + side(2)^(2) This can be reduced to h^(2) = a^(2) + b^(2) In words ; for any right angled triangle the hypotenuse squared is equal to the sum of the squares of other two sides. NB ; The hypotenuse is the longest side and opposite to the right angle. The other two sides are shorter than the hypotenuse and form the right angle.

he made the theorem C squared = A squared + B squared and A squared = C squared - B squared or B squared = C squared - A squared
The square root of 72,361 is 269. That means each number is about 90. Guessing that the numbers are 83, 89, and 97: 83 + 89 + 97 = 269, which verifies this. So the largest is 97.
9x squared-15x squared = -6
2 squared X 3 squared = 5 squared
