The value of x is
Explanation of Solution
Given Information: A
Formula used:
For a right triangle with a perpendicular being drawn to the hypotenuse(as shown below), the relation between the hypotenuse and the normal to it is expressed as,
This implies the length of the normal is the geometric mean of the two parts of the hypotenuse divided by it.
Calculation :
Consider the triangle shown below.
For the given triangle, the altitude is represented by x and the parts of the hypotenuse are 10 and 5. Thus, comparing with the general figure and formula, the value of x can be calculated as,
