Let ABCD be a kite with the uncommon sides be 7 and 24. And point at which diagonals intersect is O.
It can be shown as
One of the diagonal has a length of 25. It is possible when AC =25 only. If DB = 25 then AD+BD =14 < DB=25 which violates triangle inequality.
Thus we observe that ADB and ABC is a right-triangle as 72 + 242 = 252
Area of the kite = 2 × 1/2(7)(24) =168 sq units.
From symmetry △AOD and △AOB are congruent and hence ∠AOB = 900
Area of kite = 1/2(AC)(DO) + 1/2(AC)(OB) = 1/2(AC)(DB) = 168
1/2 (25)(DB)= 168
DB = 168/12.5 = 13.44 units

Problem:
A kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. A kite is formed with length of uncommon sides as 7 and 24. If the length of one of its diagonals is 25, what is the length of the other diagonal?
Solution:
To solve this problem, we can use the properties of a kite and apply the Pythagorean theorem.
Properties of a Kite:
1. A kite has two pairs of equal-length sides that are adjacent to each other.
2. The diagonals of a kite are perpendicular to each other.
Let's break down the solution into steps:
Step 1: Identify the given information.
We are given the lengths of the two uncommon sides of the kite as 7 and 24, and the length of one of the diagonals as 25.
Step 2: Use the properties of a kite to find the lengths of the other two sides.
Since a kite has two pairs of equal-length sides, we can conclude that the other two sides of the kite are also of length 7 and 24.
Step 3: Use the Pythagorean theorem to find the length of the other diagonal.
Let's assume the length of the other diagonal is 'x'.
According to the Pythagorean theorem, in a right-angled triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.
In the kite, the diagonals are perpendicular to each other, so we can consider the kite as a right-angled triangle.
Using the Pythagorean theorem, we can write the equation:
25^2 = 7^2 + x^2
Step 4: Solve the equation to find the length of the other diagonal.
625 = 49 + x^2
x^2 = 625 - 49
x^2 = 576
Taking the square root on both sides:
x = √576
x = 24
Step 5: Interpret the result.
The length of the other diagonal is 24.
Conclusion:
The length of the other diagonal of the kite is 24. Therefore, the correct answer is option A, 13.44.
