Jawaban : 3√41 satuan panjang

Ingat!
Rumus teorema phytagoras
c² = a² + b²
dengan
a,b = merupakan sisi-sisi lain yang saling tegak lurus
c = merupakan sisi terpanjang pada suatu segitiga siku-siku (sisi miring/hipotenusa)

Pembahasan
x² = 12² + 15²
x² = 144 + 225
x²= 369
x = ± √369
x = ± √(9 × 41)
x = ± √(3² × 41)
x = ± 3√41

karena panjang sisi segitiga tidak mungkin negatif maka x= 3√41

Jadi, nilai x adalah 3√41 satuan panjang
