58 Di un triangolo rettangolo si conoscono la misura di un cateto, che è \( a \), e la misura dell'altezza relativa all'ipote nusa, che è \( h \). Determina la misura del perimetro del triangolo. \( a\left(1+\frac{\sqrt{a^{2}-h^{2}}}{a-h}\right) \)

The Colonel spots a campfire at a bearing \( N 61^{\circ} \) E from his current position. Sarge, who is positioned 266 feet due east of the Colonel reckons the bearing to the fire to be \( N 72^{\circ} \mathrm{W} \) from his current position. Determine the distance from the campfire to each man, rounded to the nearest foot: Colonel is about Sarge is about feet away from the fire
