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).

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.
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.
he made the theorem C squared = A squared + B squared and A squared = C squared - B squared or B squared = C squared - A squared
9x squared-15x squared = -6
2 squared X 3 squared = 5 squared
