jika segitiga siku-siku PQR dengan panjang sisi siku-sikunya 30 km dan 40 km maka panjang hipotenusa dari segitiga PQR adalah

<p>Hipotenusa = √(30² + 40²)</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= √(900 + 1600)</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= √2500</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 50 km</p><p>Jadi panjang hipotenusa segitiga PQR adalah 50 km</p><p>&nbsp;</p>
