In triangle $ABC,$ $\angle B = 90^\circ.$ Point $X$ is on $\overline{AC}$ such that $\angle BXA = 90^\circ,$ $BC = 15,$ and $CX = 5$. What is $BX$?

In triangle ABC, angle B = 90o. Point X is on AC such that angle BXA = 90o, BC = 15, and CX = 5. What is BX?
BXA=90o therefore BXC=90o. BXC is a right triangle with angle BXC = 90o , CB = 15 , CX = 5.
Per Pythagoras, c2 = a2 + b2 ——>> b2 = c2 – a2
BX2 = 152 – 52
BX2 = 225 – 25
BX = sqrt(200)
BX = 14.14
Does the answer conform to the Triangle Inequality Theorem
Are CB + BX > CX 15 + 14.14 > 5
CB + CX > BX 15 + 5 > 14.14
CX + BX > CB 5 + 14.14 > 15
