The triangle EFC is notable (3k,4k,5k) so it is obvious that

Similar and then pytha. Good thought!!! I like ED = X/4 the most.

I used a similar approach. Since △FAE ~ △EDC then AF/DE = AE/CD = EF/CE → AF/(x−AE) = AE/x = 6/8 = 3/4 AE/x = 3/4 → AE = 3x/4 AF/(x−AE) = 3/4 → AF = 3x/4 − (3/4)(AE) = 3x/4 − (3/4)(3x/4) = 12x/16 − 9x/16 = 3x/16 Using Pythagorean theorem in △FAE we get: AF² + AE² = EF² (3x/16)² + (3x/4)² = 6² 9x²/256 + 9x²/16 = 36 153x²/256 = 36 153x² = 36 * 256 (3√17)x = 6 * 16 *x = 32/√17*

Respected Sir 🙏 Really your way of answering goes with the grammar of mathematics....

AFE and CDE are similar then AE = 6x/8, i.e. y = AD - ED = x - 6x/8 = 2/8x In CDE (2x/8)^2 + x^2 = 8^2 i.e. x = 32/sqrt(17)

It would be more interesting if triangle CEF would not be 90°. 😜

X=5×root 2, if the quadrilateral is a square...

X=32/(17^(1/2))

Hmmm... (32/17)√17 ?
