Penjelasan dengan langkah-langkah:
5 SOAL SAJA
1. Sisi miring = √(15²+8²)
Sisi miring = √(225+64)
Sisi miring = √289
Sisi miring = 17 cm ✔
2. x = √(25² – 7² + 10²)
x = √(625 – 49 + 100)
x = √676
x = 26 ✔
3. sudut ABC = ½ × sudut AOC
sudut ABC = 150°
2
sudut ABC = 75° ✔
4. Lp = 2 × (12 × 9 + 12 × 8 + 9 × 8)
Lp = 2 × (108 + 96 + 72)
Lp = 2 × 276
Lp = 552 cm² ✔
