X = 6.

The angle bisector theorem tells us that the ratio of the lengths of the line segments on the side the bisector intersects is the same as the ratio of the lengths of the sides adjacent to the intersected side. So using the theorem and the diagram, we can create this equation, and then solve for x.
(4x+1)/15 = 5/3
15*(4x+1)/15 = 15*5/3
4x+1 = 5*5
4x+1 = 25
4x+1-1 = 25-1
4x = 24
4x/4 = 24/4
x = 6

What is the thoerema of Pitagora ?​
stellarik [79]

The Pythagorean equation relates the sides of a right triangle in a simple way, so that if the lengths of any two sides are known the length of the third side can be found. Another corollary of the theorem is that in any right triangle, the hypotenuse is greater than any one of the other sides, but less than their sum.

hope this helped:)
