Jawaban:
t² + 8² = 17²
t² + 64 = 289
t² = 289 - 64
t² = 225
t = √225
t = 15 cm

Luas segitiga
½ × 8 × 15
4 × 15
60 cm²
Penjelasan dengan langkah-langkah:
t² = hi² - la²
t² = 17² - 8²
t² = (17 × 17) - (8 × 8)
t = ²√225
t = ²√15²
Luas = ½ × La × t
Luas = ½ × 8 × 15
Luas = 1 × 8 × 7,5
Luas = 8 × 7,5
Luas = 60 cm²
