Penjelasan dengan langkah-langkah:
Penyelesaian ☁️
1.) x+2x-15= 180°
3x - 15 = 180°
3x = 180 + 15°
3x = 195
x = 195 ÷ 3
x = 65
Maka, <QPR menjadi
= 90-65
= 25 °

2.) 2! + 10!
= ( 2×1 ) + ( 10×9×8×7×6×5×4×3×2×1 )
= 2 + ( 90×8×7×6×5×4×3×2×1 )
= 2 + ( 720×7×6×5×4×3×2×1 )
= 2 + ( 5.040×6×5×4×3×2×1 )
= 2 + ( 30.240×5×4×3×2×1 )
= 2 + ( 151.200×4×3×2×1 )
= 2 + ( 604.800×3×2×1 )
= 2 + ( 1.814.400×2×1 )
= 2 + ( 3.628.800×1 )
= 2 + 3.628.800
= 3.628.802 ✅
