The value of the length x of the right angle triangle is 25/7
How to find the unknown leg of a right triangle?
Using the Leg Rule for Right Triangles, we can easily say that we have the ratio:
7/5 = 5/x
x = (5 * 5)/7
x = 25/7
Thus, we conclude that the value of the length x of the right angle triangle is 25/7
