jawab yang 9,10,1,2,3,4,5 yaaa
Penjelasan dengan langkah-langkah:
9. RQS = 90° – 27° = 63°
10. Luas ∆ = 8 x (6+12)/2 = 72 cm²
1. 3p = 90 – 15
p = 75/3
p = 25°
2. 6x - 60 + x + 30 = 180
7x = 180+30
x = 210/7
x = 30°
3. N3 = 180° - 60° = 120°
4. Luas ∆ = 4 x 20/2 = 40 cm²
5. Keliling = 4 x √576
= 4 z 24
= 96 cm
