Jawaban:
60 cm²
Penjelasan dengan langkah-langkah:
• tinggi segitiga
t = √17² - 8²
t = √289 - 64
t = √225
t = 15
• Luas segitiga
= ½ × a × t
= ½ × 8 × 15
= 120/2
= 60
jadi, luas segitiga adalah 60 cm²
_____________________________
t² + 8² = 17²
t² + 64 = 289
t² = 289 - 64
t² = 225
t = 15 cm
===========================
Luas segitiga
½ × 8 × 15
4 × 15
