>>10862649If you used trigonometry, you would find that the cosine angle on the bottom triangle is slightly greater than the cosine angle on the top triangle, which creates a discrepancy.
If you follow along the hypotenuse on either triangle and look at the equivalent point on the hypotenuse of the other triangle, you will find that that point on the hypotenuse of the bottom triangle is a tiny bit higher than that point on the hypotenuse of the top triangle.
