In the triangle ABC, ab = 13, AC = 15, BC = 14!

In the triangle ABC, ab = 13, AC = 15, BC = 14!

Let BD length x, then CD length 14-x. let ad length y
According to the fact that the sum of the squares of the two right angles equals the square of the hypotenuse,
The binary linear equation is given
The square of x plus the square of Y equals the square of 13
The square of 14-x plus the square of Y equals the square of 15
It can be concluded that ad = 5
